概述

Description

The TLE7251VLEXUMA1 is TI’s single-channel high-side switch for automotive use. It integrates a protected power MOSFET plus control logic to switch a load on the battery rail under a microcontroller’s command, simplifying driver circuitry and protection. Key features typically include undervoltage lockout, overcurrent/short-circuit protection, thermal shutdown, and a current-limit function. It also provides diagnostic feedback (fault/diagnostic output) to help the MCU monitor load conditions. The device is designed for rugged 12–24 V automotive environments, with a wide operating input range (approximately 4.5–40 V) and protection against load dumps and EMI. The UMA1 suffix indicates a specific package/tape-and-reel variant suitable for surface-mount assembly. Common applications are driving inductive or resistive loads such as lamps, motors, pumps, and solenoids directly from an ECU.
Note: for exact electrical specs, pinout, timing, and package details, consult the TLE7251VLE datasheet and product page.

Features

Short summary of TLE7251VLEXUMA1 features (automotive LIN transceiver):
- One-channel LIN transceiver for automotive single-wire networks.
- Wide operating supply range suitable for 12/24 V systems (roughly 4.5–28 V).
- MCU interface: TXD input and RXD output for host microcontroller.
- Low-power operation with fast wake-up from sleep.
- Robust protection: short to GND or VBAT, overvoltage/undervoltage protection, reverse polarity protection, and thermal shutdown.
- ESD protection on pins; EMI-friendly with slew-rate control and current limiting.
- Diagnostic capabilities: fault/open-load/short-to-GND or short-to-VBAT indication for bus and/or TXD status.
- Wake-up features and filtering to minimize false wakes on the LIN bus.
- Automotive-grade, AEC-Q100 qualified with extended temperature range (typical -40°C to 125°C).
- Small, rugged package suitable for space-constrained automotive applications.
Note: For exact electrical specs (voltage ranges, currents, timings) and pinout, please refer to the official datasheet.

Package

The TLE7251VLEXUMA1 uses the VLE package – an 8‑pin Very Low‑profile Leadframe Package (UMA1 variant).

Pinout

- Pin count: 8 pins
- Function: Automotive LIN transceiver (physical layer). Interfaces a microcontroller to the LIN bus: provides TXD input and RXD output, LIN bus pin, supply (VBAT) and ground, plus wake-up and enable/shutdown control pins. Exact pinout depends on the package variant; consult the datasheet for mapping.
