Note: To power on the device from standby, it is recommended to: toggle INA or INB or SEL0 or
SEL1 from 0 to 1 first to come out from STBY mode; toggle PWM from 0 to 1 with a delay of
20 microsecond this avoids any overstress on the device in case of existing short-to-battery.

VNHD7008AY Protections

3 Protections

3.1 Power limitation (high-side driver)


The basic working principle of this protection consists of an indirect measurement of the
junction temperature swing Δ Tj through the direct measurement of the spatial temperature
gradient on the device surface in order to automatically shut off the output MOSFET as soon
as Δ Tj exceeds the safety level of Δ Tj_SD. The protection prevents fast thermal transient
effects and, consequently, reduces thermo-mechanical fatigue. When Power Limitation is
reached, The device enters in latch mode and generates the Fault Flag on Multisense =
VsenseH when the faulty leg diagnostic is selected (please refer to Table 13).

3.2 Thermal shutdown


In case the junction temperature of the device exceeds the maximum allowed threshold
(typically 175°C), the device enters in latch mode and generates the Fault Flag on
Multisense = VsenseH (please refer to Table 13). The concerned high side can be switched
ON again as soon as: Tj drops below TTR_HSD, INX is set low for a duration >
TLATCH_RST_HS and set high again.

3.3 High-side current limitation


The device is equipped with an output current limiter in order to protect the silicon as well as
the other components of the system (e.g. bonding wires, wiring harness, connectors, loads,
etc.) from excessive current flow. In case of short circuit, overload or during load power-up,
the output current is clamped to a safety level, ILIMH, by operating the output power
MOSFET in the active region

3.4 External PowerMOS low side VDS monitoring


The VDS_monitoring function has the ability to sense the OUTPUT Mosfet source voltage
and compare it to a predetermined threshold. This threshold is programmable, using an
internal reference current IREF_OVL_LSD = 50 µA (typ.) and an external resistor connected
at VREF_OVL_LS external pin.
This protection will be activated when the low side Power Mos is switched ON and its gate is
fully charged: to guarantee this condition the function will detect a short to battery event only
when PWM = H and after a blanking time tfil_OVL_LS= 2.2 µs (typ.) starting from PWM
rising edge. This feature is present for each LSD leg.
In case of fault conditions caused by Power Limitation or overtemperature or open
load/short to VCC in OFF state, the fault is indicated by the MultiSense pin being internally
switched to a "current limited" voltage source pulled to level VSENSEH.

VNHD7008AY MultiSense operation

5 MultiSense operation

5.1 MultiSense analog monitoring


Diagnostic information on device and load status are provided by an analog output pin
(MultiSense) delivering the following signals:
 Current monitor: current mirror of HSDx output current
 VCC monitor: voltage propotional to VCC
 TCASE: voltage propotional to chip temperature
Those signals are routed through an analog multiplexer which is configured and controlled
by means of SELx and SEn pins, according to the address map in Table 12.

5.2 Multisense diagnostics flag in fault conditions


Multisense pin delivers fixed voltage (VSENSEH) with a certain current capability in case of:
 fault condition on activated high-side triggered by Power Limitation
 fault condition on activated high-side triggered by overtemperature protection
 fault condition on VDS of Low side exceeded threshold

VREG and Driver_LS Block VNHD7008AY

6 VREG and Driver_LS Block

VREG pin is the output of an internal low drop voltage regulator. VREG block is designed to
power the driver of external power Mosfet (Driver_LS) and it allows a proper MOS transition.
 VREG out voltage will be VREG=10V if Vbattery > 10V, while VREG = Vbattery if
Vbattery < 10V.
An external capacitor CREG = 100 nF connected to the pin VREG is needed to proper
polarize the circuit (see Figure 16).

7 Reverse battery protection

CP pin provides the necessary gate drive for an external n-channel PowerMOS used for
reverse polarity protection. The external N-channel Power MOSFET used for the reverse
battery protection should have the following characteristics:
 BVdss > 20 V (for a reverse battery of -16 V);
 RDS(on) < 1/3 of H-bridge total RDS(on)
 Standard Logic Gate Driving

8 Open-load detection in off-state

The Open Load (OL) detection in off-state operates when output is deactivated (means INA
= INB = PWM=0, or INB together with PWM=0). Open load detection is performed by
reading the MultiSense output. External (switched) pull-up resistor has to be used and
dimensioned to pull output voltage above the maximum open load detection voltage (VOL
MAX) when load is not connected and as well stays below the minimum level (VOL MIN)
when load is connected.
When the open load is detected, VsenseH is indicated on Multisense pin, possible
conditions are specified in Table 14.
If pull up resistor is applied over switched circuitry, it allows to detect short to VCC from
open-load (see Figure 16).
The RPU value has to be:

V BATTmin – V OLmax
R pull_up  -----------------------------------------------------------
2  I L(off2)min [@VOLmax]

VNHD7008AY Immunity against transient electrical disturbances

9 Immunity against transient electrical disturbances

The immunity of the device against transient electrical emissions, conducted along the
supply lines and injected into the VCC pin, is tested in accordance with ISO7637-2:2011 (E)
and ISO 16750-2:2010.
The related function performance status classification is shown in Table 15.
Test pulses are applied directly to DUT (Device Under Test) both in ON and OFF-state and
in accordance to ISO 7637-2:2011(E), chapter 4. The DUT is intended as the present device
only, without components and accessed through VCC and GND terminals.
Status II is defined in ISO 7637-1 Function Performance Status Classification (FPSC) as
follows: "The function does not perform as designed during the test but returns automatically
to normal operation after the test".
