Product details

Overview

VNQ5E160K-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 limitation, and 4.5–28 V operating supply range. It drives grounded resistive/inductive/capacitive loads with integrated diagnostics, thermal shutdown with auto-restart, reverse-battery protection, and CMOS-compatible 3.0 V inputs for microcontroller interfacing in body control modules.

For engineers reviewing the VNQ5E160K-E datasheet, VNQ5E160K-E pinout, VNQ5E160K-E application, or VNQ5E160K-E equivalent, key selection criteria include per-channel open-load detection (on/off-state), short-to-VCC diagnosis, power-limiting overload protection, and STAT_DIS-enabled wired-OR diagnostic bus integration in automotive ECU designs.

Technical Context

The device implements four independent VIPower M0-5 high-side switches with active power limitation for inrush and overload management, coupled with dedicated open-drain STATUS pins per channel. Each channel features dual-mode open-load detection-voltage-based in off-state and current-threshold-based in on-state-and supports diagnostic disable via STAT_DIS to enable multi-device status bus sharing.

Protection architecture includes undervoltage shutdown (4.5 V threshold), overvoltage clamp (41–52 V), thermal shutdown at 150 °C with 7 °C hysteresis and auto-restart, and reverse-battery tolerance via external GND network. All protections feed into real-time status reporting without requiring external components for basic fault indication.

Key Specifications

Parameter	Value and Actual Design Meaning
Channels	4 independent high-side outputs with individual STATUS pins
R_ON (typ)	160 mΩ per channel at I_OUT = 1 A, T_j = 25 °C - enables low conduction loss in 12 V automotive systems
I_LIMH (typ)	10 A DC short-circuit current limit - sustains brief overloads without latch-off
V_CC Range	4.5 V to 28 V - covers cold-crank (4.5 V) to load-dump (28 V) automotive transients
Input Logic	3.0 V CMOS-compatible with 0.25 V hysteresis - ensures noise-immune interface with 3.3 V MCUs
STATUS Function	Open-drain per channel with overload, overtemp, short-to-VCC, and on/off open-load detection - enables discrete fault identification without multiplexing
Thermal Shutdown	150 °C trip with auto-restart and 135 °C reset - maintains functional continuity after transient thermal events

Pinout & Package

Package: PowerSSO-24, surface-mount, thermally enhanced with exposed VCC-connected tab for PCB heat sinking. Pin count: 24, arranged in two rows (12 per side), top-view configuration per Figure 2 of ST Doc ID 14471 Rev 4.

Pin/Terminal	Circuit Role	Design Meaning
VCC (pins 1, 11, 24)	Main supply input	Three parallel connections reduce IR drop and improve transient robustness; tab tied to VCC for thermal path
GND (pin 6)	Ground reference	Single ground pin requires external reverse-battery protection network (diode/resistor) per page 22
INPUT1–4 (pins 2, 3, 12, 13)	CMOS logic control inputs	Hysteresis (0.25 V) prevents noise-induced switching; compatible with 3.3 V and 5 V MCUs
OUTPUT1–4 (pins 7, 8, 19, 20)	High-side switched outputs	Each drives grounded loads; R_ON = 160 mΩ enables ≤1.6 W dissipation at 10 A
STATUS1–4 (pins 4, 5, 14, 15)	Per-channel diagnostic outputs	Open-drain, active-low signals report faults individually; support wired-OR when STAT_DIS enabled
STAT_DIS (pin 9)	Status disable control	Active-high CMOS input; pulling high disables all STATUS pins for multi-device bus arbitration

Key Features

Feature	Design Value
Per-channel open-load detection	Distinguishes open-circuit faults in both ON-state (current threshold <40 mA) and OFF-state (voltage threshold >2 V), eliminating need for external sense resistors
Power-limiting overload protection	Actively limits output current during short-circuit events without latching off, enabling software-controlled recovery cycles
Reverse-battery tolerant design	With external GND-line diode/resistor network (Fig 32), survives -14 V battery reversal without damage
Diagnostic bus compatibility	STAT_DIS pin allows multiple VNQ5E160K-E devices to share a single MCU interrupt line via wired-OR status aggregation
Automotive-grade ESD immunity	4 kV HBM on inputs/status pins, 5 kV on outputs/VCC - exceeds ISO 10605 requirements for under-hood ECUs

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS4H160-Q1	Higher R_ON (200 mΩ), no per-channel STATUS pins - single global FAULT pin only	Lacks individual channel diagnostics; requires external circuitry for open-load detection	Preferred where cost-sensitive designs accept reduced diagnostic granularity and simpler layout
BTS724G	Lower current limit (6 A typ), no STAT_DIS pin, different pinout (PG-DSO-28)	Not pin-compatible; lacks wired-OR capability and off-state open-load detection	Suitable for legacy platforms using BTS7xx family, but requires PCB redesign and firmware adaptation

Compared with TPS4H160-Q1 and BTS724G, the VNQ5E160K-E uniquely delivers per-channel STATUS feedback, off-state open-load detection, and STAT_DIS-enabled bus arbitration - critical for ASIL-B-compliant diagnostics in modern BCMs without adding external logic.

FAQ

What is the maximum continuous output current per channel?

The VNQ5E160K-E does not specify a fixed maximum continuous current; instead, it uses active power limitation with a typical DC short-circuit current limit (I_LIMH) of 10 A. Actual continuous current depends on PCB thermal design, ambient temperature, and duty cycle - for example, at T_amb = 85 °C with 200 cm² copper area, sustained 5 A per channel is achievable per Figure 36 thermal data.

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

Off-state open-load detection measures output voltage (V_OL) relative to a 2–4 V threshold while the channel is disabled. If V_OUT > V_OL, the STATUS pin asserts low after 200–1200 µs delay (t_POL), indicating an open circuit. This relies on internal biasing and comparator circuitry - no external pull-up or sense resistor required.

Can STAT_DIS be left unconnected, and what is its default behavior?

No - STAT_DIS must not be left floating. Per Table 2, it must be either pulled high through a 10 kΩ resistor or driven actively. Default (unconnected) is undefined and risks erratic STATUS behavior. When pulled high, all STATUS pins enter high-impedance state, enabling wired-OR connection with other drivers on the same diagnostic bus.

Is reverse-battery protection internal or external?

Reverse-battery protection is external: the VNQ5E160K-E requires an external diode or resistor network in the GND line (per Figure 32 and Section 3.1) to survive -14 V battery reversal. The IC itself includes internal ESD protection (4 kV HBM on GND) but no reverse-polarity blocking element - this design choice optimizes forward-conduction efficiency and thermal performance.
