Description

TPS923654DMTR is a Texas Instruments LED-driver IC designed to power multiple LED strings with constant current. It integrates a switching regulator and per-channel current regulation, enabling stable LED brightness from a single input source. Key features typically include dimming options (PWM/analog), protection features (short/open LED, overvoltage, thermal), and suitability for automotive and general lighting applications. The DMTR suffix indicates the Tape-and-Reel package version. For exact electrical specs (number of channels, current rating, input voltage range, dimming interfaces), see the TI datasheet.

Features

Key features of TPS923654DMTR (concise):
- Multi-channel constant-current LED driver
- Programmable current per channel (external sense resistors)
- I2C-compatible control interface for dimming and status
- Dimming options: analog dimming and PWM dimming
- Wide input voltage range suitable for automotive and general LED applications
- High efficiency with integrated switching regulator
- Robust protection: overcurrent/short-circuit, overvoltage, UVLO, thermal shutdown, LED open protection
- Fault/status reporting via dedicated pins or flags
- Small DMTR package, RoHS compliant
Note: Always consult the latest datasheet for exact channel count, voltage ranges, and register map.

Package

8-pin MSOP package (MSOP-8), Tape & Reel.

Pinout

Pin count: 16 pins (16‑pin package, e.g., MSOP/TSSOP variant).
Function: Multi‑channel constant‑current LED driver with six outputs; provides adjustable LED current (ISET), dimming (PWM/analog), and protection features (open/load/over‑temp) for LED backlighting.
