Product details

Overview

VNQ5E160AK-E from STMicroelectronics is a quad-channel automotive high-side driver in PowerSSO-24 package, delivering 160 mΩ on-resistance per channel, 10 A typical current limit, and analog current sense with ±12% ratio drift over temperature. It drives grounded 12 V resistive/inductive/capacitive loads-including LEDs-with integrated diagnostics and protection for body control modules.

For engineers reviewing the VNQ5E160AK-E datasheet, VNQ5E160AK-E pinout, VNQ5E160AK-E application, or VNQ5E160AK-E equivalent, key selection criteria include its 4.5–28 V operating range, CMOS-compatible 3.0 V inputs, off-state open-load detection, short-to-V_CC diagnosis, and thermal shutdown with auto-restart-critical for ASIL-B–compatible power distribution systems.

Technical Context

The device integrates four independent VIPower M0-5 high-side switches with dedicated analog current sense pins (CS1–CS4) and a shared CS_DIS enable input. Each channel implements active power limitation during inrush/overload, with real-time current mirroring (K₀ = 330–870 A/A) and fault flagging via voltage drop thresholds.

Protection logic combines undervoltage lockout (V_USD = 4.5 V), overvoltage clamp (41–52 V), reverse-battery tolerance (via external GND network), and thermal shutdown at 150 °C with 135 °C auto-restart hysteresis. Diagnostics include off-state open-load detection, short-to-V_CC identification, and proportional current sense disable capability.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - withstands load-dump transients up to ISO 7637-2 Pulse 5a without external clamping
Operating voltage range	4.5 V to 28 V - supports cold-crank (4.5 V) and boosted battery (28 V) conditions in automotive environments
On-state resistance	160 mΩ (typ, 25°C) - limits conduction loss to ≤256 mW at 4 A, enabling thermally constrained PCB layouts
Current limit (typ)	10 A - sustains short-circuit events with active power limitation, preventing thermal runaway
Off-state supply current	2 µA (typ) - enables ultra-low-power sleep modes in always-on vehicle domains
Current sense accuracy	±12% full-scale drift (–40°C to 150°C) - provides reliable fault discrimination across engine bay temperatures
Turn-off delay	10 µs (typ) - ensures fast de-energization of inductive loads (e.g., solenoids, fuel injectors)

Pinout & Package

Package: PowerSSO-24 - thermally enhanced exposed-tab SO-24 variant with integrated heat slug connected to V_CC, optimized for automotive under-hood thermal management (R_thj-case = 8 °C/W max).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary power rail; connects to exposed thermal tab for low-impedance heat path to PCB copper
GND	Ground reference	Reverse-battery protected node requiring external diode/resistor network per Figure 32
INPUT1–4	CMOS-compatible control inputs	3.0 V logic threshold with 0.25 V hysteresis; tolerate ±1 mA drive current
OUTPUT1–4	High-side switched outputs	Drive grounded loads; feature V_ON clamping (25 mV) and reverse diode (0.7 V @ 1 A)
CURRENT SENSE1–4	Analog current mirror outputs	Deliver I_SENSE = I_OUT/K (K = 330–870); support external resistor sharing when CS_DIS = high
CS_DIS	Current sense enable/disable	Active-high CMOS input; disables all CS pins simultaneously to reduce system-level sensing overhead

Key Features

Feature	Design Value
Inrush current management	Active power limitation prevents peak current surges during capacitive load turn-on, eliminating need for external NTCs
Proportional current sense	Four independent analog outputs with <12% full-scale drift enable precise load monitoring and predictive failure analysis
Off-state open-load detection	Validates load continuity before activation using internal bias current-no external pull-up required
Short-to-V_CC diagnosis	Distinguishes output short-circuited to battery from normal operation via differential voltage sensing
Thermal shutdown with auto-restart	Shuts down at 150 °C and resumes after cooling to 135 °C, maintaining system availability during transient overloads

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	Single-channel, 160 mΩ R_ON, no analog current sense; uses digital SPI diagnostics	Lacks per-channel analog sense; requires MCU with SPI interface instead of analog ADC	Preferred when system-level diagnostics are centralized and board space permits discrete channel count scaling
VNQ7E160AJTR-E	Quad-channel, 160 mΩ R_ON, identical pinout but 5 V CMOS-only inputs (no 3 V compatibility)	Requires 5 V logic interface; lacks 3.0 V input compatibility for mixed-voltage MCUs	Select when legacy 5 V microcontrollers are used and 3 V input support is unnecessary

Compared with VNQ5E160AK-E, TPS4H160-Q1 trades analog diagnostics for digital configurability and channel scalability, while VNQ7E160AJTR-E matches pinout and R_ON but sacrifices 3 V logic compatibility-making the original optimal for new designs requiring low-voltage MCU interfacing and analog fault visibility.

FAQ

What is the maximum continuous output current per channel?

The VNQ5E160AK-E does not specify a continuous current rating independent of thermal conditions. Its 10 A typical current limit (I_LIMH) is a short-circuit protection threshold activated during overload. Continuous current capability depends on PCB copper area, ambient temperature, and switching duty cycle-up to ~4 A is sustainable with adequate heatsinking per the PowerSSO-24 thermal data (R_thj-amb ≈ 30 °C/W on 25 cm² copper).

How does off-state open-load detection work without external components?

Each OUTPUT pin sources a 1–5 µA internal test current when inactive. If the load remains connected to ground, this current flows and pulls the output voltage near GND; if the load is disconnected, the output floats to V_CC, triggering detection. No external pull-up or sensing resistor is needed-functionality is fully integrated and validated across –40°C to 150°C.

Can CS_DIS be used to multiplex current sense signals from multiple VNQ5E160AK-E devices?

Yes. When CS_DIS is driven high, all four CURRENT SENSE pins enter high-impedance state, allowing external circuitry (e.g., shared op-amp or ADC input) to monitor multiple devices sequentially. The datasheet confirms this mode enables "sharing of the external sense resistor with other similar devices," reducing BOM cost and board area in multi-driver systems.

Is reverse-battery protection built-in or externally implemented?

Reverse-battery protection is externally implemented: the GND pin must be connected through either a series resistor (R_GND) or diode (D_GND) as shown in Figure 32. The IC itself tolerates –0.3 V on V_CC but relies on this external network to block reverse current flow into the substrate-ensuring compliance with ISO 16750-2 requirements.
