Product details

Overview

VND5E160AJ-E from STMicroelectronics is a dual-channel high-side driver IC for 12V automotive grounded loads, featuring analog current sense per channel, 160 mΩ on-state resistance (typ.), 10 A current limitation (typ.), and integrated diagnostics including open-load detection, short-to-VCC sensing, and thermal shutdown with autorestart. It operates from 4.5 V to 28 V and delivers precise load control in body electronics modules.

For engineers reviewing the VND5E160AJ-E datasheet, VND5E160AJ-E pinout, VND5E160AJ-E application, or VND5E160AJ-E equivalent, this device supports critical automotive safety-critical load switching where real-time current monitoring, fault reporting, and robust protection against reverse battery, load dump, and thermal runaway are required.

Technical Context

The VND5E160AJ-E integrates two independent VIPower M0-5 high-side switches with dedicated analog current sense outputs (CS1/CS2) and a shared CS_DIS enable pin. Each channel implements active power limitation during inrush and overload, with proportional current sense ratio (K1 = 370 typ.) calibrated across -40°C to 150°C.

Diagnostic logic monitors output voltage, current, and junction temperature to generate fault signals via current sense pin behavior-e.g., VSENSEH = 8 V during overtemperature or short-to-VCC-and supports ON/OFF state open-load detection using internal comparators referenced to 2–4 V thresholds.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - withstands automotive load-dump transients without external clamping
Operating voltage range	4.5 V to 28 V - supports cold-crank (4.5 V) and full-battery (28 V) conditions
On-state resistance	160 mΩ (typ. at 25°C) - limits conduction loss to ≤250 mW at 1 A, enabling compact thermal design
Current limit threshold	10 A (typ. at 13 V) - actively regulates peak load current during short-circuit events
Standby supply current	2 µA (off-state) - enables always-on modules without battery drain
Current sense accuracy	±13% K1 drift over -40°C to 150°C - enables reliable fault classification across full automotive temperature range
Thermal shutdown	150°C trip, 135°C reset - provides safe autorestart after transient overloads

Pinout & Package

Supplied in PowerSSO-12 package: thermally enhanced 12-pin surface-mount housing with exposed die-pad connected to VCC for low R_thj-case (8 °C/W).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary power rail; connects to exposed tab for thermal conduction and reverse-battery protection path
GND	Ground reference	Must be externally protected against reverse battery via diode/resistor network per Figure 32
INPUT1 / INPUT2	Digital control inputs	CMOS-compatible (3.0 V logic), with 0.25 V hysteresis to reject noise in automotive environments
OUTPUT1 / OUTPUT2	High-side switched outputs	Drive grounded resistive/inductive/capacitive loads; each includes active clamp and demag energy handling
CURRENT SENSE1 / CURRENT SENSE2	Analog diagnostic outputs	Deliver proportional current (I_OUT/K ≈ 370–520) for real-time load monitoring and fault identification
CS_DIS	Current sense disable control	Active-high CMOS input; disables both sense channels to share external sense resistor across multiple devices

Key Features

Feature	Design Value
Inrush current management	Active power limitation prevents fuse blowing during capacitive load turn-on
Proportional analog current sense	Two independent sense channels with <13% gain drift over full temp range support accurate fault discrimination
Off-state open-load detection	Identifies disconnected loads with 2–4 V threshold without requiring external components
Reverse battery protection	Integrated ESD and clamp structures plus GND network compatibility prevent damage from -12 V misconnection
Over-temperature autorestart	Shuts down at 150°C and resumes operation at 135°C, avoiding permanent latch-off in intermittent faults

Applications

Rear Combination Lamp

Engine Bay Auxiliary Loads

Use Scenario: Switching brake lights, turn signals, and fog lamps subject to vibration, moisture, and thermal cycling.

IC Role / Device Role / Timing Role: Robust high-side driver with short-to-VCC detection and thermal foldback for lamp filament and LED loads.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
VND5E025AK-E	Lower R_ON (25 mΩ), single-channel, same PowerSSO-12 package	Higher current capability (36 A peak), but lacks dual-channel integration and shared CS_DIS	Select when higher efficiency and single-load precision outweigh need for dual-channel consolidation
TPS4H160-Q1	4-channel, 160 mΩ R_ON, SPI interface, no analog current sense	Offers programmable diagnostics and fault masking via register access, but requires MCU firmware overhead	Select when system-level configurability and multi-device synchronization are prioritized over analog simplicity

Compared with VND5E160AJ-E, the VND5E025AK-E trades dual-channel integration for lower conduction loss in single-load systems, while the TPS4H160-Q1 replaces analog sense with digital configurability-making VND5E160AJ-E optimal for cost-sensitive, dual-load automotive nodes requiring direct analog feedback.

FAQ

What is the maximum continuous output current per channel?

The VND5E160AJ-E does not specify a fixed maximum continuous current; instead, it implements active current limitation at 10 A (typ.) during overload or short-circuit conditions. Continuous current capability depends on PCB copper area, ambient temperature, and thermal management-up to ~4.5 A per channel is sustainable with adequate heatsinking per Figure 36.

How does the current sense function work during fault conditions?

During faults-including overload, short-to-ground, short-to-VCC, or overtemperature-the current sense pin (CS1/CS2) transitions to a high-voltage fault state (VSENSEH = 8 V) or high-current state (ISENSEH = 9 mA), distinct from normal proportional operation. This allows MCU firmware to distinguish between nominal load current and specific fault types without additional signal conditioning.

Can CS_DIS be used to multiplex current sense signals from multiple VND5E160AJ-E devices?

Yes. Pulling CS_DIS high disables both current sense outputs, allowing external circuitry (e.g., shared sense resistor + op-amp) to monitor aggregate load current. The datasheet confirms this mode supports sharing with "other similar devices," and timing delays (tDSENSE1H/L) ensure clean enable/disable transitions without signal contention.

Is reverse battery protection implemented internally or externally?

Reverse battery protection requires external implementation: the GND pin must be protected using either a series resistor (RGND) or series diode (DGND) per Figure 32. While the device includes internal ESD structures and clamp diodes, it does not integrate full reverse-polarity blocking-this external network prevents damage during -12 V battery connection.
