Automotive single-channel LED driver - TPS92613-Q1
Datasheet
 

Description

With LEDs being widely used in automotive applications, simple LED drivers are more and more popular. Comparing to discrete solutions, a low-cost monolithic solution lowers system-level component count and significantly improves current accuracy and reliability.

The TPS92613-Q1 device is a single-channel, high-side LED driver operating from an automotive car battery. It is a simple, yet elegant, solution to deliver constant current for a single LED string with full LED diagnostics. The one-fails–all-fail feature is able to work together with other LED drivers, such as the TPS9261x-Q1, TPS9263x-Q1, and TPS92830-Q1 devices, to address different requirements.

Features

  • AEC-Q100-qualified for automotive applications:
    • Temperature grade 1: –40°C to +125°C, TA
  • Wide input voltage range: 4.5 V to 40 V
  • Low quiescent and low fault-mode current: typical 200 µA
  • Single high-precision current regulation:
    • ±4.6% Accuracy over full junction temperature range
    • Constant current adjustable by external sense resistor
    • Up to 600 mA maximum current
    • Brightness control by input PWM duty cycle
  • Heat sharing with external resistor
  • Low dropout voltage (sense-resistor voltage drop included):
    • Maximum dropout: 150 mV at 10 mA
    • Maximum dropout: 400 mV at 70 mA
    • Maximum dropout: 700 mV at 150 mA
    • Maximum dropout: 1.3 V at 300 mA
  • Diagnostics and protection:
    • LED open-circuit and short-circuit detection with auto-recovery
    • Diagnostic enable with adjustable threshold for low-dropout operation
    • Fault bus up to 15 devices, configurable as either one-fails–all-fail or only-failed-channel-off (N-1)
    • Thermal shutdown
  • Operating junction temperature range: –40°C to +150°C
