STMicroelectronics VN5E025AJTR-E

Overview

VN5E025AJTR-E from STMicroelectronics is a single-channel automotive high-side driver in PowerSSO-12 package, integrating analog current sense, power-limiting overload protection, and CMOS-compatible 3 V/5 V logic interface. It delivers 60 A short-circuit current limit, 25 mΩ on-resistance at 25°C, and operates across 4.5–28 V supply range for 12 V grounded loads including LEDs, solenoids, and relays.

For engineers reviewing the VN5E025AJTR-E datasheet, VN5E025AJTR-E pinout, VN5E025AJTR-E application, or VN5E025AJTR-E equivalent, key selection criteria include its proportional current sense accuracy (±10% drift over -40°C to 150°C), thermal shutdown with auto-restart, reverse battery protection support, and off-state open-load detection capability.

Technical Context

The device implements active power limitation via dynamic output voltage drop control during overload or short-to-ground events, enabling precise thermal management without external circuitry. Its VIPower M0-5 process integrates high-voltage DMOS output stage with embedded diagnostic comparators and hysteresis-controlled input logic.

Current sensing uses a dedicated proportional I_OUT/I_SENSE ratio (typ. 3050 at 0.5 A) referenced to an external sense resistor, with CS_DIS pin enabling shared-sense-resistor configurations. Fault reporting includes separate analog indicators for overtemperature (T_J ≥ 150°C), short-to-VCC (t_DSTKON = 180–1200 µs), and OFF-state open load (V_OL = 2–4 V threshold).

FAQ

What is the function of the CS_DIS pin?

The CS_DIS pin is an active-high CMOS-compatible input that disables the CURRENT SENSE pin's analog output and reduces sense leakage current to zero. When pulled high, it allows multiple VN5E025AJTR-E devices to share a single external sense resistor, simplifying PCB layout and reducing BOM count in multi-channel systems.

How does the device handle reverse battery conditions?

VN5E025AJTR-E itself is not reverse-battery tolerant on the GND pin; instead, it requires external protection-either a series resistor (RGND) or Schottky diode (DGND) in the ground path-as specified in Section 3.1 of the datasheet. This design prevents latch-up and permanent damage while maintaining full functionality during battery reversal events.

Can this device drive inductive loads like fuel injectors?

Yes. The device supports inductive demagnetization energy up to 140 mJ (at V_CC = 13.5 V, L = 0.8 mH) and includes active V_DEMAG clamping (V_CC−41 V). Its 40 µs turn-off delay and controlled dV/dt ensure safe flyback management without external snubbers in typical injector drive circuits.

What is the significance of the "TR" suffix in VN5E025AJTR-E?

The "TR" suffix indicates tape-and-reel packaging (per Figure 41), optimized for automated SMT assembly. It denotes 2,500 units per reel, moisture sensitivity level (MSL) 3, and compliance with JEDEC J-STD-020 reflow profiles-ensuring compatibility with high-volume automotive electronics manufacturing lines.
