TPS92630QPWPRQ1 Datasheet PDF - TI

The TPS9263x-Q1 devices are three-channel linear LED drivers with analog and PWM dimming control. Their full-diagnostic and built-in protection capabilities make them the ideal solution for variable-intensity LED lighting applications up to the medium-power range.

●The design of this device suits it well for driving LEDs configured as a single string or multiple strings within its power capability. A single device can drive up to three strings with one to three LEDs in each string at a total current of up to 150 mA per channel. Outputs can be paralleled to provide higher current drive capability to 450 mA.

●In multiple-string applications, the device offers the advantage of having common-cathode connection of the LED strings. So, the application needs is only a single return wire instead of one return wire per LED string that a system with low-side current sense would need.

●A single-LED short comparator allows detection of single LED failing with a short circuit. Fault output can support bus connection topology between multiple ICs.

●The included temperature monitor reduces the LED drive current if the IC junction temperature exceeds a thermal threshold. One can program the temperature threshold through an external resistor. One can disable the thermal current-monitor feature by connecting the TEMP pin to ground. Output of the junction temperature as an analog voltage is available as a factory program option.
