... SO14 Power Package 1. Description The T6818 is a fully protected driver interface designed in 0.8-µm BCDMOS technol- ogy. They are used to control different loads by a microcontroller in automotive and industrial applications. Each of the 3 high-side and 3 low-side drivers is capable to drive currents up to 1.5 A. ...

... Inhibit 0 V applied to pin 10 (INH) inhibits the T6818. All output switches are then turned off and switched to tri-state. The data in the output register are deleted. The current consumption is reduced to less than 5 µA at pin VS and less than 25 µA at pin VCC. The output switches can be activated again by switching pin 10 (INH which initiates an internal power-on reset ...

... GND pins. Negative spikes at the output pins (e.g. negative spikes caused by an inductive load switched off with a high side driver) may activate the overtemperature protection function of the T6818. In this condition, all outputs will be switched off simultaneously. If this behavior is not acceptable or compatible with your application functionally necessary, that for switching on required outputs again, the SRR bit (Status Register Reset) is set, to ensure a reset of the over- temperature function ...
