Product details

Overview

VN5E160ASO-E from STMicroelectronics is a single-channel automotive high-side driver IC using VIPower® M0-5 technology, designed to switch 12 V grounded resistive/inductive/capacitive loads with integrated analog current sensing, thermal shutdown, overvoltage clamp, and short-circuit protection. It features 160 mΩ on-state resistance, 10 A typical current limit, 2 µA standby current, and 3.0 V CMOS-compatible input logic.

For engineers reviewing the VN5E160ASO-E datasheet, VN5E160ASO-E pinout, VN5E160ASO-E application, or VN5E160ASO-E equivalent, this device is selected for precise load control in automotive body electronics where diagnostic feedback, reverse-battery resilience, and AEC-Q100 compliance are mandatory.

Technical Context

The VN5E160ASO-E implements a power MOSFET-based high-side switch with active power limitation for inrush and overload management, coupled with real-time proportional current sense (K₀ = 490 typ.) referenced to ground via dedicated CS pin. Its protection architecture includes undervoltage lockout (4.5 V), overtemperature shutdown with auto-restart (150 °C trip), and bidirectional fault detection-short-to-VCC, OFF-state open-load, and short-to-ground.

Diagnostic functionality is enabled through configurable CS_DIS pin control, allowing shared external sense resistor usage across multiple channels. The device operates across 4.5–28 V supply range, supports 13.5 V load-dump transients, and integrates ESD protection (HBM 4 kV on IN/CS/CS_DIS) and reverse-battery protection via external GND network.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - withstands automotive load-dump transients without external clamping
On-state resistance	160 mΩ @ 25°C - enables low conduction loss at 10 A continuous output
Current limit (typ)	10 A - self-limiting during short-circuit events to prevent thermal runaway
Standby current	2 µA - minimizes battery drain in vehicle sleep modes
Operating voltage range	4.5 V to 28 V - covers cold-crank (4.5 V) to boosted alternator (28 V) conditions
Current sense ratio	490 (I_OUT/I_SENSE) - delivers accurate analog feedback for microcontroller-based diagnostics
Thermal shutdown	150 °C with auto-restart - recovers after cooling below 135 °C, enabling fault-tolerant operation

Pinout & Package

Package: SO-16L (16-pin small outline, exposed pad for thermal dissipation; R_thj-pcb = 18.5 °C/W).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Accepts 4.5–28 V DC; clamped to 46 V internally during overvoltage events
OUT	High-side power output	Drives grounded loads; features V_ON limitation (25 mV) and reverse diode (0.7 V drop)
GND	Ground reference	Must be protected externally against reverse battery via diode/resistor network per datasheet Fig. 3.1
IN	CMOS-compatible control input	Hysteresis-enabled (0.25 V), 3.0 V logic compatible; drives internal gate driver
CS	Analog current sense output	Delivers proportional I_SENSE = I_OUT/K₀; supports fault detection down to 25 mA
CS_DIS	Current sense disable enable	Active-high CMOS input; disables CS pin to share external sense resistor across multiple drivers

Key Features

Feature	Design Value
Inrush current management	Active power limitation prevents peak current surges during capacitive load turn-on
Proportional current sensing	±11% full-range drift over -40°C to +150°C enables reliable closed-loop load monitoring
OFF-state open-load detection	Validates load continuity before activation, reducing false fault reporting in dormant systems
Reverse battery protection	Requires external GND network but tolerates -0.3 V on VCC and -200 mA on GND pin
AEC-Q100 qualification	Qualified to Grade 0 (-40°C to +150°C junction), meeting automotive reliability and stress-test requirements

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS4H160-Q1	Higher R_ON (200 mΩ), no analog current sense output - uses digital SPI diagnostics	Lacks proportional analog feedback; requires MCU with SPI interface instead of ADC	Preferred when system-level diagnostics are handled via serial bus and thermal margin allows higher conduction loss
VNQ5E160K-E	Quad-channel version in PowerSSO-24 package; identical per-channel specs and sense ratio	Designed for multi-load integration; shares same die but different pinout and thermal footprint	Selected when consolidating four independent loads into one package to reduce PCB area and assembly cost

Compared with TPS4H160-Q1, VN5E160ASO-E provides direct analog current feedback for simpler ADC-based monitoring, while VNQ5E160K-E offers channel density at the expense of layout flexibility and thermal coupling between outputs.

FAQ

What is the maximum continuous output current rating for VN5E160ASO-E?

The device is rated for 10 A typical DC current limit under short-circuit conditions, with thermal derating applied above 25°C ambient. Continuous safe operating current depends on PCB copper area and airflow; with 2-layer board and 18.5 °C/W R_thj-pcb, sustained 5 A is achievable at 85°C case temperature per datasheet Figure 36.

How does the CS_DIS pin affect current sensing functionality?

Pulling CS_DIS high disables the internal current sense amplifier, disconnecting the CS pin from the output stage. This allows sharing of a single external sense resistor across multiple VN5E160ASO-E devices, reducing component count and PCB space in multi-channel designs without sacrificing diagnostic capability.

Is external reverse-battery protection required for VN5E160ASO-E?

Yes - the device requires an external diode or resistor network on the GND pin to withstand reverse battery conditions, as specified in Section 3.1 of the datasheet. While VCC tolerates -0.3 V, GND must be protected against -200 mA reverse current to prevent latch-up or permanent damage.

Can VN5E160ASO-E drive inductive loads like fuel injectors without external flyback diodes?

No - although it includes V_DEMAG clamping (VCC − 46 V) and handles up to 36 mJ demagnetization energy, external flyback diodes are still recommended for high-energy inductive loads to ensure reliable voltage clamping and avoid exceeding absolute maximum ratings during fast turn-off.
