概述

Description

TPS9901TPZPRQ1 is a Texas Instruments voltage supervisor/reset IC (part of the TPS990x family). It monitors a supply rail and provides a deterministic reset signal to a microcontroller or digital logic, helping ensure proper startup and brown-out protection in embedded systems.
Key idea:
- Detects undervoltage and asserts a reset when the rail is out of range; releases reset when the voltage is stable.
Typical features (device variants vary): undervoltage thresholds, reset assertion and release timing, and a robust reset output. Some versions may include optional manual reset or watchdog functionality.
Package/ordering note:
- The TPZPRQ1 suffix denotes the package type and RoHS/tape-and-reel options; consult the datasheet for exact packaging.
For precise electrical specs (supply range, threshold options, timing, reset polarity, pinout), refer to the TPS9901 datasheet and TI product page.

Features

TPS9901TPZPRQ1 features (concise):
- I2C-controlled LED driver with programmable constant-current sinking
- Dimming: PWM and register-based brightness control
- Protection: open LED, LED short, overcurrent, and thermal shutdown
- Fault reporting/flag output for with-system wakeup or monitoring
- UVLO and power-on reset for reliable startup
- Low quiescent current in standby; suitable for battery-powered apps
- Wide LED-supply range and small, RoHS-compliant package (TPZPRQ1)
Note: For exact electrical specs (current range, I2C speeds, number of channels, voltage ranges), please refer to the official datasheet.

Package

An 8-pin VSSOP (Very Small Outline Package) package, automotive-grade (Q1).

Pinout

- Pin count: 8 pins (8-lead package)
- Function: Single-channel constant-current LED driver (LED current sink) with sense/feedback and dimming input support (PWM/analog) for driving an LED string.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: An American multinational semiconductor company that designs, manufactures, and sells analog and embedded processing ICs and other semiconductor products for automotive, industrial, and consumer electronics markets.

Application

TPS9901TPZPRQ1 is a constant‑current LED driver IC. Typical application areas include:
- Automotive and industrial LED indicators/backlights
- LCD display backlighting
- Signage, architectural, and decorative lighting
- Portable/battery-powered LED lighting and wearables
- General-purpose low‑to‑mid‑power LED lighting in consumer electronics
It provides regulated current with protection features (short-circuit, overtemperature) suitable for these applications.
