STMicroelectronics VND7004AYTR

Overview

VND7004AYTR from STMicroelectronics is a double-channel automotive smart high-side driver in PowerSSO-36 package, featuring MultiSense analog feedback, 4 mΩ typical R_ON per channel, 100 A current limitation, and operation across 4–28 V supply range. It drives 12 V grounded resistive/inductive loads (e.g., headlamps, glow plugs) via 3 V/5 V CMOS-compatible inputs with integrated diagnostics and protection.

For engineers reviewing the VND7004AYTR datasheet, VND7004AYTR pinout, VND7004AYTR application, or VND7004AYTR equivalent, key selection criteria include multi-channel high-side drive capability, analog current/voltage/temperature sensing on a single pin, latch-off configurability via FaultRST, and compliance with automotive load protection requirements including reverse battery and ESD.

Technical Context

The VND7004AYTR integrates two independent VIPower® M0-7 high-side switches with shared diagnostic architecture. Each channel delivers precise current limiting (100 A typ), thermal shutdown with configurable latch-off, and active power limitation during overload-enabling robust management of fast thermal transients without external circuitry.

Its MultiSense output multiplexes three analog signals-load current (via high-precision proportional current mirror), V_CC, and T_CHIP-onto one pin, with dedicated Sense Enable control for OFF-state diagnosis disablement and external sense resistor sharing. FaultRST provides hardware-based fault reset or latch-off disable.

FAQ

What is the purpose of the SENSE_EN pin on VND7004AYTR?

The SENSE_EN pin disables OFF-state open-load detection and reduces quiescent current during system low-power modes. When pulled low, it disconnects the internal sense circuitry from the SENSE pin, allowing shared external sense resistors across multiple devices and minimizing standby power consumption in vehicle sleep states.

How does the FaultRST pin function during thermal shutdown?

During thermal shutdown, VND7004AYTR latches off unless FaultRST is actively pulled low. Holding FaultRST low for ≥100 µs resets the latch and re-enables the output if temperature has dropped below the hysteresis threshold. This enables either automatic retry or host-controlled recovery depending on system architecture.

Can VND7004AYTR drive inductive loads like fuel injectors without external flyback protection?

Yes-the device integrates active clamp circuitry that safely dissipates inductive kickback energy during turn-off. Its built-in overvoltage clamp and self-limiting thermal response eliminate the need for external flyback diodes or TVS devices when driving typical automotive solenoids and injectors within rated voltage and current limits.

Is the MultiSense analog output compatible with standard 12-bit microcontroller ADCs?

Yes-SENSE output delivers ratiometric analog signals (0–V_CC) with guaranteed monotonicity and ±5% accuracy across temperature. With proper external RC filtering and sampling timing aligned to multiplexing sequence (per datasheet timing diagrams), it interfaces directly with 12-bit MCUs such as STM32G4 or RH850 without signal conditioning.
