Application Information
Enable/Disable CONTROL
The EN pins control the state of the two switches. AP22966 is enabled when the EN pins are asserted high, and, the device is disabled when EN
pins are asserted low. The EN input is compatible with both TTL and CMOS logic. This pin cannot be left floating and must be tied either high or
low for proper functionality.

INPUT CAPACITOR
To limit the voltage drop on the input supply when the switch turns on into a discharged load capacitor resulting in a transient inrush current, a
NEW PRODUCT

capacitor needs to be placed between VIN and GND. Use 1μF capacitor or a larger value for high-current applications. Place the capacitor close
to the VIN pins.

OUTPUT CAPACITOR
The recommended output capacitor value is 0.1μF when switching lighter loads. For heavier loads close to 6A, it is recommended that the VIN and
VOUT trace lengths be kept to a minimum. In addition, a bulk capacitor (≥ 10μF) may also be placed close to the VOUT pins. If using a bulk
capacitor on VOUT, it is important to control the inrush current by choosing an appropriate soft-start time in order to minimize the droop on the
input supply.

SOFT-START TIME
A capacitor on the SS pins (to GND) sets the slew rate for each channel. To ensure desired performance, a capacitor with a minimum voltage
rating of 25V should be placed on the SS pins. The input inrush current can be controlled by choosing an appropriate soft-start time. The table
below shows the rise-time (10% to 90%) on VOUT for a variety of VIN and CSS conditions.

Soft-start Time (µs) 10% - 90%, VBIAS = 5V, CL = 0.1µF, CIN = 1µF, RL = 10Ω, Typical Values are at TA=+25°C

THERMAL CONSIDERATOIN
The maximum junction temperature should be restricted to +125°C under normal operating conditions. The maximum allowable power dissipation
PD(MAX) can be calculated as:
PD(MAX) = (TJ(MAX) - TA) / θJA
where,
TJ(MAX) is the maximum operating junction temperature. For AP22966, TJ(MAX) = 125°C
TA is the ambient temperature of the device
θJA is the junction-to-air thermal impedance

BOARD LAYOUT
Good PCB layout is important for improving the thermal performance of the device. All trace lengths should be kept as short as possible. Place
input and output capacitors close to the device to minimize the effects of parasitic inductance. The input and output PCB traces should be as wide
as possible. Use a ground plane to enhance the power dissipation capability of the device.
