Short circuit detected: set high, when at least one output is switched off by a
13 SCD
short circuit condition
Inhibit: this bit is controlled by software (bit SI in input register) and hardware
14 INH
inhibit (pin 17). High = standby, low = normal operation
15 PSF Power supply fail: undervoltage at pin VS detected
Note: Bit 0 to 15 = high: overtemperature shutdown

4595E–BCD–09/05
3.2 Power Supply Fail
In case of undervoltage at pin VS, an internal timer is started. When the undervoltage delay time
(tdUV) programmed by the SCT bit is reached, the power supply fail bit (PSF) in the output regis-
ter is set and all outputs are disabled. When normal voltage is present again, the outputs are
enabled immediately. The PSF bit remains high until it is reset by the SRR bit in the input
register.
3.6 Inhibit
There are two ways to inhibit the T6816:
1. Set bit SI in the input register to zero
2. Switch pin 17 (INH) to 0V
In both cases, all output stages are turned off but the serial interface stays active. The output
stages can be activated again by bit SI = 1 or by pin 17 (INH) switched back to 5V.
