TPS61196PWPRQ1

Overview

The TPS61196PWPRQ1 is a six-string white LED driver IC designed for automotive applications, featuring independent PWM dimming for each channel. It operates with an input voltage range of 8 V to 30 V and delivers up to 400 mA output current per string. The device supports a maximum output voltage of 120 V and includes short circuit and thermal protection mechanisms.

Feature Summary

• Independent PWM dimming control for each of the six LED strings
• Integrated short circuit and thermal protection for enhanced reliability
• AEC-Q100 qualified for automotive environment compliance

Applications

• Automotive exterior lighting systems
• LED backlighting modules
• High-brightness indicator arrays

Procurement Notes

Verify AEC-Q100 qualification status and HTSSOP-28 package availability through official Texas Instruments channels. Confirm RoHS compliance and humidity sensitivity handling requirements prior to procurement. Ensure supply chain authenticity by sourcing directly from authorized distributors or the manufacturer.

Selection Notes

Select this component for designs requiring precise individual string control in multi-channel LED architectures. Consider the 8 V to 30 V input range and 120 V output capability when matching power supply constraints. Evaluate thermal management needs given the 400 mA per channel rating and operating temperature range of -40°C to +125°C.

Part Context

This part belongs to the TPS61196 family of high-voltage LED drivers. It is specifically engineered for automotive-grade performance, distinguishing it from commercial variants through rigorous qualification standards. The PWPR suffix indicates the HTSSOP-28 package configuration with reel packaging.

Replacement Considerations

Consult Texas Instruments documentation for direct pin-compatible alternatives within the TPS61196 series. Verify electrical parameter equivalence before substituting with other manufacturers' components.
