STMicroelectronics VN5T016AH-E

Overview

VN5T016AH-E from STMicroelectronics is a single-channel high-side driver with integrated analog current sense, designed for 24 V automotive loads (e.g., solenoids, lamps, valves). It delivers 60 A current limiting, 16 mΩ typical R_ON, and fault reporting via proportional I_SENSE output. Its HPAK package supports high-power dissipation in engine control units and body electronics.

For engineers reviewing the VN5T016AH-E datasheet, VN5T016AH-E pinout, VN5T016AH-E application, or VN5T016AH-E equivalent, key selection criteria include latch-off thermal/overload protection, CMOS-compatible 3.0 V input logic, reverse battery immunity, and ±5% current sense accuracy across –40°C to 150°C.

Technical Context

This device implements ST's VIPower® M0-7 technology to integrate power MOSFET, protection circuitry, and analog current sensing in one die. It uses active clamp architecture to limit V_OUT during inductive turn-off and features dual-threshold thermal shutdown (150°C trip, 135°C reset) with hysteresis.

The FR_Stby pin enables hardware-based fault reset and standby mode entry; low-level assertion clears latch-off conditions (overload, overtemperature), while sustained low on IN and FR_Stby forces ultra-low 2 µA supply current. Current sense ratio (K₀–K₆) is calibrated across six load ranges for <±26% drift over temperature.

FAQ

What is the maximum continuous output current rating for VN5T016AH-E?

The device does not specify a continuous DC current rating due to thermal dependence on PCB layout and ambient conditions. Instead, it guarantees 60 A typical current limitation during short-circuit events and supports sustained loads up to 15 A with proper heatsinking (R_thj-amb ≤ 25 °C/W). Derating curves in Figure 27 define safe operating area based on copper area and airflow.

How does the FR_Stby pin function during normal operation versus fault recovery?

During normal operation, FR_Stby must be held high (≥2.1 V) to enable output switching. When an overload or thermal shutdown occurs, the output latches off and FR_Stby must receive a clean low pulse (≤0.9 V, ≥2 µs width) to reset the channel. Holding FR_Stby low continuously places the device in 2 µA standby mode, disabling all outputs.

Can VN5T016AH-E drive inductive loads without external flyback diodes?

Yes - the integrated V_DEMAG clamp (V_CC−58 V to V_CC−70 V) safely dissipates demagnetization energy from inductive loads like solenoids and relays. This eliminates the need for external flyback diodes in most 24 V automotive applications, provided the load's stored energy (½LI²) stays below 390 mJ (per datasheet Section 2.1).

What is the recommended sense resistor value for accurate current measurement?

A 3.9 kΩ resistor on the CS pin yields 5 V full-scale output at 20 A (K₆ = 4240 typ), matching standard MCU ADC references. For lower-current ranges (e.g., 0.1–2 A), use 10 kΩ to maximize resolution at sub-amp levels while maintaining V_SENSE < 5 V. Layout must minimize trace inductance to avoid oscillation on the CS node.
