SLIS178B October 2017 – January 2018 TPS92830-Q1
Once the channel has asserted a short-to-GND fault, it automatically retries periodically. In PWM mode, the device sources I(Retry_short) through the SENSEx pin to pull up the LED loads with a pulse duration of t(SG_retry_ON). The device waits for t(SG_retry_OFF) until the next retry pulse. Once auto retry detects that the short-to-GND fault is removed, the device resumes normal operation. During auto retry mode, the device ignores PWM inputs.
