STMicroelectronics VN5E010MH-E

Overview

VN5E010MH-E from STMicroelectronics is a single-channel automotive high-side driver in HPAK package, integrating VIPower M0-5 technology for 12 V grounded loads. It delivers 85 A typical current limiting, 10 mΩ ON-state resistance at 25 °C, and analog current sense with ±15% ratio drift over temperature - enabling real-time load monitoring in engine control units and body electronics.

For engineers reviewing the VN5E010MH-E datasheet, VN5E010MH-E pinout, VN5E010MH-E application, or VN5E010MH-E equivalent, key selection criteria include its 4.5–28 V operating range, CMOS-compatible 3 V/5 V inputs, thermal shutdown with autorestart, reverse battery protection, and proportional current sense with CS_DIS disable functionality.

Technical Context

The device implements active power limitation to manage inrush and overload currents, using internal thermal sensing and dynamic voltage drop control to sustain 85 A short-circuit current while limiting junction temperature rise. Its diagnostic architecture routes proportional I_OUT/I_SENSE ratio (3000–12000) to the CS pin, with fault indication via output clamping and current sense voltage shift above 8 V during overtemperature or power limitation events.

Protection logic combines undervoltage shutdown (4.5 V threshold), overvoltage clamp (41–52 V), loss-of-ground/VCC detection, and ESD-hardened inputs (4 kV HBM). The CS_DIS pin enables shared external sense resistor usage by disabling analog current feedback without affecting switching operation.

FAQ

What is the maximum continuous load current the VN5E010MH-E can drive?

The device is not rated for continuous current beyond its thermal limits. At 25 °C ambient with adequate PCB copper area (≥1000 mm²), it supports ~15 A continuous due to R_thj-amb = 67.7 °C/W and 150 °C max junction temperature. Derating is required above 70 °C ambient - consult Figure 33 for R_thj-amb vs. copper area curves.

How does the CS_DIS pin affect diagnostic functionality?

Pulling CS_DIS ≥2.1 V disables analog current sense output (CS pin goes high-impedance), halting I_SENSE generation while preserving all switching and protection functions. This allows shared external sense resistors across multiple VN5E010MH-E devices in multi-channel designs without signal interference.

Can the VN5E010MH-E operate with a 3.3 V microcontroller I/O?

Yes - the IN pin accepts 3 V CMOS logic with guaranteed VIH ≥2.1 V and VIL ≤0.9 V, and includes 0.25 V hysteresis for noise immunity. No level-shifting circuitry is needed when interfacing with 3.3 V MCUs such as STM32G4 or NXP S32K1.

What failure modes trigger the thermal shutdown with autorestart?

Autorestart activates after junction temperature exceeds 150 °C (TTSD), causing immediate output turn-off. Output re-enables only when junction cools to ≤135 °C (TRS), providing 15 °C hysteresis. This sequence repeats during sustained overload - software must limit activation cycles to ensure long-term reliability per Table 8 notes.
