... Serial Data Interface, Daisy Chain Capable MHz Clock Frequency • SO14 Power Package 1. Description The T6818/ATA6828 are fully protected driver interfaces designed in 0.8-µm BCD- MOS technology. 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/ATA6828. 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/ATA6828. 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 switch- ing on required outputs again, the SRR bit (Status Register Reset) is set, to ensure a reset of the overtemperature function ...
