DESCRIPTION
1
SDATA
I/O
3.3V CMOS Digital I/O; serial data line that carries configuration and monitoring information to and from the Intersil
ISL6590 digital controller via the shared controller interface bus. Information transmitted via SDATA
includes: PVID information, input UVLO fault, output under/over voltage fault, thermal shutdown fault,
peak current limit setpoint, ATRH and ATRL trip levels
2
PWM
I
3.3V CMOS Digital input; pulse width modulation input to the high side driver.
3
NDRIVE
I
3.3V CMOS
Digital input; multifunction pin used for assigning device ID at startup. During operation, provides
pulse width modulation for the low side driver
