... DO TP S1L S1H T6818/T6828 4 Data transfer starts with the falling edge of the CS signal. Data must appear at DI syn- chronized to CLK and are accepted on the falling edge of the CLK signal. LSB (bit 0, SRR) has to be transferred first. Execution of new input data is enabled on the rising edge of the CS signal ...

... By writing a high to the SRR bit in the input register the SCD bit is reset and the disabled outputs are enabled applied to pin 10 (INH) inhibits the T6818/T6828. 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 µ ...

... 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 func- tion of the T6818/T6828. 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 overtemperature function ...
