Visão Geral
Description
TPS923654DMTR is a Texas Instruments constant-current LED driver IC. It regulates LED string current from a DC input with high efficiency, using a compact external-component design. The part supports dimming (PWM or analog) and includes fault protection (overcurrent/short/open, thermal) suitable for automotive and general lighting applications. DMTR denotes the packaging/packaging option (tape-and-reel). For exact electrical specs, application circuits, and limits, consult the TI TPS923654 datasheet.
Features
Here are typical features of the TPS923654DMTR (TI LED driver):
- One-channel constant-current buck LED driver for automotive/industrial LED strings
- Wide input voltage range (high enough for automotive applications; up to ~65 V)
- External resistor sets LED current (programmable current)
- Dimming: supports PWM and DC dimming options for brightness control
- Protections: short-to-LED protection, open-LED protection, UVLO, overvoltage, thermal shutdown
- Fault handling: automatic protection with status/fault indication
- High efficiency with low quiescent current and soft-start
- Built-in current regulation and simple external components
- Small DMTR package for compact designs
Note: exact electrical specs (max LED current, dimming range, efficiency, timing) are in the TI datasheet. Please refer to TPS923654DMTR datasheet for precise numbers and allowed operating conditions.
