STMicroelectronics VN5160STR-E

Overview

VN5160STR-E from STMicroelectronics is a single-channel automotive high-side driver IC designed for controlling resistive, inductive, and capacitive loads connected to ground. It features 160 mΩ on-state resistance (R_ON), 5.4 A typical current limitation (I_LIMH), 4.5–36 V operating supply range, and integrated open-load detection in both on- and off-states - enabling robust load monitoring in body control modules and lighting systems.

For engineers reviewing the VN5160STR-E datasheet, VN5160STR-E pinout, VN5160STR-E application, or VN5160STR-E equivalent, key selection criteria include its SO-8 package thermal performance (R_thj-amb per Figure 32), CMOS-compatible 3.0 V logic input, reverse battery protection capability, and diagnostic status pin behavior under thermal shutdown and output stuck-to-V_CC conditions.

Technical Context

This device implements VIPower M0-5 technology to integrate power MOSFET, protection circuitry, and diagnostics in a monolithic high-side switch. Its active power limitation manages inrush current without external components, while dual-mode open-load detection (on-state current threshold ≤40 mA; off-state voltage threshold ≥2 V) enables fault isolation across load states.

The STATUS pin operates as an open-drain diagnostic output with configurable disable via STAT_DIS, supporting system-level fault reporting with timing delays (t_POL = 200–1000 µs, t_SDL = 20 µs). Thermal shutdown triggers at 150–200 °C with 7 °C hysteresis and automatic restart after cooling below 135–140 °C.

FAQ

What is the maximum continuous output current rating for VN5160STR-E?

The VN5160STR-E does not specify a fixed maximum continuous current; instead, it uses self-limiting current protection with I_LIMH = 5.4 A (typ.) at V_CC = 13 V. Continuous current capability depends on PCB thermal design: with 100 mm² copper area, junction temperature remains within 150 °C up to ~3.2 A at 85 °C ambient (per Figure 32 and Table 5). Derating is required above 85 °C ambient.

How does the STATUS pin behave during thermal shutdown?

During thermal shutdown (T_j > 150–200 °C), the STATUS pin asserts low after a 20 µs delay (t_SDL) and remains low until junction temperature falls below the reset threshold (135–140 °C). The pin returns to normal diagnostic operation once thermal recovery completes - no manual reset or power cycle is needed.

Can VN5160STR-E drive inductive loads without external flyback diodes?

No - an external freewheeling diode must be placed across the inductive load (cathode to V_CC, anode to OUTPUT) to safely dissipate demagnetization energy. The device's V_DEMAG clamp (V_CC−41 V) only handles low-energy transients; unclamped inductive kickback exceeds absolute maximum ratings and risks permanent damage.

Is the STAT_DIS pin mandatory for functional operation?

No - STAT_DIS is optional. When left floating or tied to GND, STATUS operates normally as an open-drain output. When driven high (≥2.1 V), STATUS enters high-impedance state, allowing multiple drivers to share a common diagnostic bus. This feature enables scalable diagnostic architecture without additional logic gates.
