TPS65177RHAR

TPS65177RHAR is a Texas Instruments power-management IC (PMIC) in the TPS6517x family. It is designed to generate the bias and regulator rails used by display panels (LCD/OLED) in portable devices, and is commonly applied in smartphones, tablets, and embedded displays. The device typically integrates multiple DC–DC converters, LDOs, and sequencing logic to provide required rails, with programmable outputs, soft-start, and power-up sequencing. It includes protection features such as short-circuit/overcurrent and thermal shutoff, and supports enable control and fault reporting. RHAR denotes a specific TI packaging/reel option for this part. For exact electrical specifications, pinout, and recommended circuits, consult the official TPS65177RHAR datasheet and TI product page.

TPS65177RHAR features (concise):
- Quad-channel constant-current LED sink driver for backlighting
- Per-channel current regulation (adjustable via I2C registers)
- Serial control interface (I2C) for current, dimming, and sequencing
- PWM and group/individual dimming capabilities
- Soft-start to minimize inrush during turn-on
- LED open/short protection with diagnostic/status reporting
- Fault protections: overcurrent, overvoltage, thermal shutdown
- Undervoltage lockout and power-on reset
- Wide input voltage range with low quiescent current
- RoHS-compliant packaging in 28-pin HTSSOP (RHAR)
Note: For exact electrical limits and register map, please refer to the TPS65177RHAR datasheet.

- Pin count: 28 pins (TPS65177RHAR in a 28‑pin package, RHAR code).
