STMicroelectronics VND5004ATR-E

Overview

VND5004ATR-E from STMicroelectronics is a double-channel 4 mΩ high-side driver with integrated analog current sense, AEC-Q100 qualified for automotive power distribution. It delivers 100 A typical current limiting, operates from 4.5 V to 27 V supply, features reverse battery protection with self-switch-on, and provides proportional load current sensing via dedicated CURRENT SENSE pins-used in body control modules for driving solenoids, relays, and LED arrays.

For engineers reviewing the VND5004ATR-E datasheet, VND5004ATR-E pinout, VND5004ATR-E application, or VND5004ATR-E equivalent, key selection criteria include on-resistance (4 mΩ), thermal shutdown behavior (150 °C trip), CS_DIS-controlled analog sense enable/disable, and PQFN-12x12 package thermal performance under sustained 70–100 A loads.

Technical Context

This device implements VIPower M0-7 technology with dual independent high-side switches, each integrating active power limitation, inrush management, and real-time thermal monitoring. Its analog current sense ratio (K1 = 12,730 typ. at 25 °C) enables precise closed-loop load monitoring without external shunts.

The architecture includes bidirectional VCC clamp (41–52 V), loss-of-ground/loss-of-VCC detection, and cyclic self-switching during load dump transients (ISO 7637-2 Pulse 5b). Protection logic couples thermal shutdown (TTSD = 150 °C) with automatic restart and overtemperature sense output (VSENSEH = 9 V).

FAQ

What is the maximum continuous output current per channel?

The VND5004ATR-E does not specify a fixed maximum continuous current; instead, it limits output current to 100 A typical (ILIMH) during short-circuit events. Continuous current capability depends on PCB thermal design: with 78 mm × 78 mm copper area, it supports ≥35 A per channel at 150 °C junction temperature, per thermal data in Table 5.

How does the current sense function behave when CS_DIS is high?

When CS_DIS is driven high (≥2.1 V), both CURRENT SENSE pins enter high-impedance state (leakage <5 µA), effectively disconnecting the internal current mirror. This prevents loading of external sense circuitry and reduces quiescent power during diagnostic sleep modes or non-monitoring intervals.

Is the VND5004ATR-E pin-compatible with the VND5004A-E?

No - VND5004ATR-E uses the PQFN-12x12 Power lead-less package, while VND5004A-E uses MultiPowerSO-30. They share identical electrical functionality and pin functions but differ in physical layout, thermal pad configuration, and soldering profile. PCB redesign is required for substitution.

Does the device support PWM operation?

Yes - the VND5004ATR-E supports PWM switching up to 25 kHz (based on td(on)/td(off) ≤35 µs and thermal constraints). For sustained PWM, thermal design must ensure junction temperature remains below 150 °C; recommended minimum copper area is 78 mm × 78 mm with 2 oz Cu for 10 A RMS at 50% duty cycle.
