Feature Description (continued)
If device detects an internal fault, it pulls the FAULT output LOW with constant current to signal a fault alarm on
the one-fails–all-fail fault bus. To avoid false triggering, TI recommends not to directly connect the FAULT output
using off-board connectors.
7.3.2 Constant-Current Driver
The TPS92610-Q1 device has a high-side constant-current integrated driver. The device senses channel current
with an external high-side current-sense resistor, R(SNS). A current regulation loop drives an internal transistor
and regulates the current-sense voltage at current-sense resistor to V(CS_REG). When the output driver is in
regulation, the output current can be set using the following equation.

7.3.3 Device Enable
The TPS92610-Q1 device has an enable input EN. When EN is low, the device is in sleep mode with ultralow
quiescent current I(Shutdown). This helps to save system-level current consumption in applications where battery
voltage directly connects to the device without high-side switches.
7.3.4 PWM Dimming
The TPS92610-Q1 device supports PWM output dimming via PWM input dimming and supply dimming.
The PWM input functions as an enable for the output current. When the PWM input is low, the device also
disables the diagnostic features.
Supply dimming applies PWM dimming on the power input. For an accurate PWM threshold, TI recommends
using a resistor divider on the PWM input to set PWM threshold higher than V(POR_rising).
7.3.5 Diagnostics
The TPS92610-Q1 device provides advanced diagnostics and fault protection features for automotive exterior
lighting systems. The device is able to detect and protect from LED string short-to-GND, LED string open-circuit
and single-LED short scenarios. It also supports a one-fails–all-fail fault bus that could flexibly fit different
legislative requirements.
7.3.5.1 Short-to-GND Detection
The TPS92610-Q1 device has LED short-to-GND detection. Short-to-GND detection monitors the output voltage
when the channel is in the ON state. Once a short-to-GND LED failure is detected, the device turns off the output
channel and retries automatically. If the retry mechanism detects removal of the LED short-to-GND fault, the
device resumes normal operation.
The device monitors the V(OUT) voltage and compares it with the internal reference voltage to detect a short-to-
GND failure. If V(OUT) falls below V(SG_th_rising) longer than the deglitch time of t(SG_deg), the device asserts the
short-to-GND fault and pulls FAULT low. During the deglitching time period, if V(OUT) rises above V(SG_th_falling), the
timer is reset.
Once the device has asserted a short-to-GND fault, the device turns OFF the output channel and sources a
small current I(retry) from IN to OUT to pull up the LED loads continuously. Once auto retry detects output voltage
rising above V(SG_th_falling), it clears the short-to-GND fault and resumes normal operation. Once the device
detects a short-to-GND fault, the device retries automatically, ignoring the PWM input.
Once an LED short-to-GND failure is detected, the constant-current source pulls the fault bus down.
7.3.5.2 Open-Circuit Detection
The TPS92610-Q1 device has LED open-circuit detection. Open-circuit detection monitors the output voltage
when the channel is in the ON state. Open-circuit detection is only enabled when DIAGEN is HIGH.
