STMicroelectronics VND5E160MJ-E

Overview

VND5E160MJ-E from STMicroelectronics is a double-channel high-side driver IC for automotive 12 V grounded loads, featuring integrated analog current sense per channel, 160 mΩ typical R_ON, 10 A typical current limitation, and full protection suite including overtemperature shutdown with auto-restart, undervoltage/overvoltage clamping, and reverse-battery tolerance. It serves as a smart power switch in body control modules for LED lighting, solenoids, and resistive/inductive actuators.

For engineers reviewing the VND5E160MJ-E datasheet, VND5E160MJ-E pinout, VND5E160MJ-E application, or VND5E160MJ-E equivalent, key selection criteria include dual-channel CMOS-compatible 3 V/5 V input interface, proportional current sense accuracy across -40 °C to 150 °C, PowerSSO-12 thermal performance (R_thj-case = 8 °C/W), and diagnostic enable/disable via CS_DIS pin.

Technical Context

The device implements two independent VIPower™ M0-5 high-side switches with active power limitation for inrush and overload management, coupled with dedicated analog current sense circuitry delivering I_OUT/I_SENSE ratios from 270 to 730 (±13% drift over temperature). Each channel features hysteresis on IN pins and internal clamp diodes for ESD and transient immunity.

Protection logic integrates thermal shutdown at 150–200 °C with 7 °C hysteresis, undervoltage lockout at 4.5 V (0.5 V hysteresis), and output voltage drop limitation to 25 mV at 30 mA. Fault signals are conveyed through current-sense pin behavior-e.g., V_SENSEH = 5 V or I_SENSEH = 9 mA under overload or overtemperature conditions.

Key Specifications

Pinout & Package

Housed in the PowerSSO-12 package (exposed tab connected to V_CC), the device uses a 12-pin surface-mount configuration with integrated heat sink via the exposed metal pad.

FAQ

What is the maximum allowable reverse battery voltage the VND5E160MJ-E can withstand?

The device itself is not reverse-battery rated; however, with an external protection network (e.g., 1 kΩ resistor or Schottky diode in the GND line per Figure 29), it withstands -14 V reverse polarity per ISO 16750-2. The absolute maximum rating for reverse V_CC is -0.3 V, so external GND-side protection is mandatory for automotive deployment.

How does the current sense disable (CS_DIS) function affect diagnostic capability?

When CS_DIS is pulled high, both CS1 and CS2 outputs are disabled, halting analog current feedback. This allows sharing of a single external sense resistor among multiple VND5E160MJ-E devices in modular systems. Diagnostics revert to digital flags only (e.g., thermal shutdown indication via output behavior), losing continuous current measurement resolution.

Can the VND5E160MJ-E drive inductive loads like fuel injectors without external flyback protection?

No external flyback diode is needed: the device integrates an active overvoltage clamp (V_clamp = 41–52 V) and demagnetization energy handling (EMAX = 34 mJ per pulse). It safely manages inductive kickback from injectors or solenoids up to L = 12 mH and I = 10 A, as validated in Figure 31 and Section 3.5.

What is the thermal derating behavior above 100 °C case temperature?

R_ON increases to 320 mΩ at 150 °C junction (Table 5), raising conduction loss. Current limit (I_LIML) drops to 2.5 A during thermal cycling (Table 8), and thermal shutdown activates at 150–200 °C. Designers must use Figure 33 to size PCB copper area for R_thj-amb ≤ 30 °C/W to sustain 10 A at 105 °C ambient.
