概述

Description

TPS929240AQDCPRQ1 is TI’s automotive four-channel smart high-side switch. It combines four independent load switches with protection and diagnostics in one device, intended for car electrical systems.
Key points:
- Four high-side switches with integrated FETs for separate loads
- Protection: overcurrent/short-circuit, undervoltage lockout, thermal shutdown, reverse-battery protection
- Diagnostics: per-channel status/fault reporting; enables per channel
- Operation: PWM-ready, supports on/off control, suitable for automotive loads
- Wide automotive range: designed for vehicle voltage environments (typical broad supply range)
- Qualification: automotive-grade device (AEC-Q100 qualified)
Typical uses: lamp drivers, actuators, relays, and other car LOAD applications where multiple channels need protection and diagnostics in a compact package.
For exact electrical specs, pinout, and protection details, refer to the TPS929240AQDCPRQ1 datasheet and TI product page.

Features

TPS929240AQDCPRQ1 is an automotive high-side switch. Key features include:
- Single-channel high-side switch with built-in current limit and short-circuit protection
- Reverse-current blocking when off to prevent backfeeding
- Enable/shutdown input with undervoltage lockout
- Overvoltage and undervoltage protection
- Thermal (overtemperature) protection
- Low quiescent current in OFF state and fast turn-on
- Robust ESD protection and transient/ load-dump robustness
- Automotive-grade (AEC-Q100 qualified)
- Small, rugged packaging options (DCP/QFN style; package code AQDCPRQ1)
- Fault indication/diagnostics where supported by the device variant
Note: exact current-limit value, voltage range, and diagnostics can vary; check the datasheet for the precise specifications of this variant.

Package

An 8-pin DCP DFN package (DFN-8).

Pinout

Pin count: 8 pins.
Function: TPS929240AQDCPRQ1 is a high-side load switch with protection. It provides controlled on/off power to a load, with current limit, overcurrent/short-circuit protection, and reverse-current protection, typically enabled/disabled via an EN input.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: A multinational American semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits and related products for electronics. TI is headquartered in Dallas, Texas.
