STMicroelectronics VND5004A-E

Overview

VND5004A-E from STMicroelectronics is a dual-channel 4 mΩ high-side driver with integrated analog current sense, AEC-Q100 qualified for automotive power management. It delivers 100 A typical current limiting, operates from 4.5 V to 27 V supply, and features reverse battery protection, load dump clamping up to 41 V transient, and thermal shutdown with automatic restart - deployed in engine control modules for solenoid and fuel injector drive.

For engineers reviewing the VND5004A-E datasheet, VND5004A-E pinout, VND5004A-E application, or VND5004A-E equivalent, key selection criteria include on-resistance stability over temperature, proportional current sense accuracy (K1 = 12,730 typ.), CS_DIS-controlled analog output impedance, and compliance with ISO 7637-2 Pulse 5b load dump transients under real vehicle battery conditions.

Technical Context

This device implements VIPower M0-3 technology with two independent high-side switches sharing a common ground-referenced load architecture. Each channel integrates active power limitation during inrush, self-limiting fast thermal transients, and bidirectional overvoltage clamp (VCC clamp = 41–52 V) that protects against load dump without external TVS.

The analog current sense path delivers ISENSE = IOUT / K1 (K1 = 12,730 typ. at Tj = 25°C), disabled via CMOS-compatible CS_DIS input. Diagnostic outputs include thermal shutdown indication and undervoltage lockout (VUSD = 4.5 V) with 0.5 V hysteresis - enabling closed-loop fault recovery in safety-critical ECU subsystems.

FAQ

What is the maximum continuous output current per channel?

The VND5004A-E does not specify a fixed continuous current rating due to thermal dependence on PCB layout and ambient conditions. At T_j = 150°C with 78 mm × 78 mm copper area, it sustains ~25 A continuous per channel. Derating is required above 100°C case temperature; full 100 A is only valid for short-circuit conditions with thermal shutdown intervention.

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 sense transistor. This prevents loading of external ADC inputs and eliminates quiescent current in diagnostic sleep modes - confirmed in Table 10 and Figure 4 of the datasheet.

Can VND5004A-E drive inductive loads without external flyback diodes?

No. While the device integrates VCC clamp and demagnetization energy handling (EMAX = 342 mJ), it does not provide internal freewheeling paths. External flyback diodes or RC snubbers are mandatory across inductive loads (e.g., solenoids, relays) to manage back-EMF and prevent voltage overshoot beyond the 41 V clamp threshold.

Is the thermal shutdown reset behavior configurable?

No. Thermal shutdown is fully autonomous: it activates at T_j = 150°C (typ.) and resets automatically when junction temperature falls to ~135°C (TR = TRS + 5°C). There is no register, pin, or external component to adjust trip or reset points - this behavior is hardwired in the VIPower die and validated per AEC-Q100 stress testing.
