概述

Description

TPS65177RHAR is a Texas Instruments multi-rail power-management IC (PMIC) in the TPS6517x family. It is designed for battery-powered devices (e.g., cameras, portable electronics) to generate and regulate multiple rails with sequencing, protection, and monitoring.
Key features (typical):
- Multiple buck regulators with adjustable outputs
- LDOs and monitoring/diagnostic features
- I2C control/status reporting
- Power sequencing and soft-start
- Protections: UVLO, overcurrent, overtemperature, fault reporting
Common benefits:
- Reduces BOM and board space, improves efficiency and Rail-to-rail sequencing in compact devices.
RHAR packaging note:
- RHAR is TI’s package/packaging code; see the datasheet for the exact pinout, footprint, and tape-and-reel details.
For exact rail counts, voltage ranges, current capability, and electrical specs, consult the TPS65177RHAR datasheet and TI reference designs.

Features

TPS65177RHAR is TI’s multi-rail power-management IC for portable devices. Key features (concise):
- Multi-rail PMIC with integrated regulators (buck regulators and/or load switches) for core and I/O rails
- Additional LDOs for sensitive rails
- I2C control interface for programming and monitoring
- Programmable power-on sequencing with ramp-rate control
- Fault protection: overcurrent/short-circuit, overvoltage, UVLO, thermal shutdown
- Power-good/power-on-reset signaling
- Low quiescent current for extended battery life
- RoHS-compliant RHAR package (HTSSOP-style) with related pin count
Note: Exact regulator count, output voltages, and electrical specs vary by revision. Refer to the TPS65177RHAR datasheet for precise numbers.

Package

TPS65177RHAR comes in a VQFN-28 package (4×4 mm) with an exposed pad.

Pinout

Pin count: 16 pins (VSSOP-16 package typically used for TPS65177RHAR).
Function: Four-channel, constant-current LED backlight driver with I2C control (brightness/dimming, fault protection, etc.) for LCD/display backlights.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- Type of company: American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits for industrial, automotive, consumer, and communications markets.

Application

TPS65177RHAR is a multi‑rail PMIC used in portable devices. Typical application areas include:
- Mobile/consumer electronics (smartphones, tablets, wearables)
- Camera modules and imaging systems
- Display backlight and indicator LED driving
- IoT and portable sensors
- Systems requiring power sequencing, multiple rails, and efficient battery-powered operation
These use cases exploit its integrated regulators, LED drivers, and sequencing capabilities for compact, energy-efficient power management.
