Product details
Overview
VNQ5160K-E from STMicroelectronics is a quad-channel automotive high-side driver IC designed for controlling resistive, inductive, and capacitive loads connected to ground. It features 160 mΩ typical on-state resistance per channel, 5.4 A current limitation (typ), 4.5–36 V operating supply range, and integrated open-load detection in both on/off states-used in body control modules for headlight, fog light, and HVAC blower actuation.
For engineers reviewing the VNQ5160K-E datasheet, VNQ5160K-E pinout, VNQ5160K-E application, or VNQ5160K-E equivalent, key selection criteria include diagnostic status signaling via open-drain STATUS pins, reverse battery protection compatibility, ISO 7637-2 transient immunity, and thermal shutdown with automatic restart under sustained overload.
Technical Context
The VNQ5160K-E integrates four independent VIPower™ M0-5 high-side switches with dedicated CMOS-compatible INPUTn and STATUSn pins per channel, plus a shared STAT_DIS pin to disable all STATUS outputs. Each channel implements active power limitation during inrush and short-circuit events, with self-limiting thermal response up to 150 °C junction temperature before shutdown.
It provides dual-mode open-load detection: on-state detection triggered when load current falls below 10–40 mA, and off-state detection activated when output voltage exceeds 2–4 V relative to ground. Protection includes undervoltage lockout (4.5 V threshold), VCC clamp up to 41 V, and output stuck-to-VCC detection with 180–500 µs delay.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 4 independent high-side switches with individual input and status pins |
| RON (per channel) | 160 mΩ @ IOUT = 1 A, Tj = 25 °C - enables low conduction loss for 5 A continuous loads |
| ILIMH | 5.4 A typ @ VCC = 13 V - sets safe short-circuit current limit before thermal intervention |
| VCC Range | 4.5 V to 36 V - supports 12 V and 24 V automotive battery systems including cold-crank down to 4.5 V |
| Open-load detection | On-state: 10–40 mA threshold; Off-state: 2–4 V threshold - enables fault isolation without external sensing |
| STATUS interface | Open-drain, CMOS-compatible with 0.5 V max VOL @ 1.6 mA - directly interfaces with 3.3 V/5 V microcontrollers |
| Transient immunity | ISO 7637-2 Pulse 1 (−75 V), Pulse 2a (+37 V), Pulse 3b (+75 V) - certified for automotive load-dump and coupling events |
Pinout & Package
Package: PowerSSO-24 (exposed thermal pad tied to VCC), surface-mount, RoHS-compliant ECOPACK® package with 24-pin top-view configuration and integrated heat dissipation path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (pins 10, 12, 24) | Power supply input | Primary battery connection; clamped to 41 V max; powers internal logic and gate drivers |
| GND (pin 11) | Ground reference | System ground return; requires external reverse-battery protection network (diode/resistor) |
| INPUT1–4 (pins 1, 3, 13, 15) | Digital control inputs | CMOS-compatible (VIH = 2.1 V, VIL = 0.9 V); each controls one high-side switch independently |
| OUTPUT1–4 (pins 2, 4, 14, 16) | High-side power outputs | Drives loads connected between OUTPUTn and GND; RON = 160 mΩ ensures <1 V drop at 5 A |
| STATUS1–4 (pins 5, 7, 17, 19) | Diagnostic status outputs | Open-drain signals indicating on/off open-load, overtemperature, or undervoltage - pulled high externally |
| STAT_DIS (pin 20) | Status disable control | Active-high CMOS input; when high, forces all STATUS pins into high-impedance state |
| TAB (exposed pad) | Thermal & electrical connection | Internally bonded to VCC; must be soldered to PCB copper pour for thermal management and EMI reduction |
Key Features
| Feature | Design Value |
|---|---|
| Inrush current management | Active power limiting prevents voltage droop and EMI spikes during cold-load turn-on of lamps or solenoids |
| Off-state open-load detection | Identifies broken-wire faults with 2–4 V threshold while output is disabled - no wake-up current required |
| Reverse battery protection support | Compatible with external GND-line diode/resistor networks (per Figure 18) to survive −14 V transients |
| Thermal shutdown with auto-restart | Shuts down at 150 °C, resets at 135 °C - enables fault recovery without MCU intervention after transient overload |
| Low standby current | 2 µA off-state supply current - meets automotive module sleep-mode requirements (e.g., LIN node quiescent budget) |
Applications
| Headlamp Control Module | HVAC Blower Driver |
|---|---|
|

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 RON, 40 V abs max, but lacks per-channel STATUS and off-state open-load detection | Suitable for simpler point-of-load switching where diagnostics are handled centrally | Select when channel count >1 is not required and system-level diagnostics suffice |
| BD82002FV-M | Quad-channel, 120 mΩ RON, 28 V max VCC, no VCC clamp above 28 V or ISO 7637-2 Pulse 1 rating | Limited to 12 V systems without load-dump robustness; no reverse battery support circuitry guidance | Prefer only in cost-sensitive 12 V non-critical applications lacking harsh transient requirements |
Compared with TPS4H160-Q1 and BD82002FV-M, the VNQ5160K-E uniquely delivers full per-channel diagnostics (on/off open-load, thermal, UVLO), 41 V VCC clamp, and validated ISO 7637-2 immunity - making it the only option qualified for ASIL-B-compliant body electronics requiring autonomous fault reporting.

FAQ
What is the maximum continuous output current per channel?
The VNQ5160K-E supports 5.4 A typical current limitation (ILIMH) under steady-state conditions at VCC = 13 V and Tj = 25 °C. Continuous current capability depends on PCB copper area and ambient temperature; with 250 cm² double-sided copper, it sustains 3.5 A per channel at 85 °C ambient. Derating curves are provided in Figure 32.
How does off-state open-load detection work without drawing load current?
Off-state detection measures output voltage relative to ground while the channel is disabled. If VOUT exceeds 2–4 V (per Table 10), the STATUS pin asserts low after 200–1000 µs delay - confirming an open circuit. This occurs with zero load current flow, consuming only 2 µA total device supply current in standby.
Can STAT_DIS be left unconnected, or must it be driven?
STAT_DIS may be left floating per Table 3, but ST recommends connecting it to VCC via a 10 kΩ resistor for deterministic behavior. When floating, internal pull-down ensures STATUS pins remain active; driving STAT_DIS high disables all STATUS outputs into high-impedance mode - useful during MCU reset or diagnostic silence periods.
Is reverse battery protection built-in, or does it require external components?
Reverse battery protection is not internal; the VNQ5160K-E requires external GND-line protection as shown in Figure 18 - either a series resistor (RGND) or Schottky diode (DGND). This design allows optimization for leakage vs. voltage drop and is validated for −14 V transients with appropriate component selection.
