Product details

Overview

VNQ810PEP-E from STMicroelectronics is a quad-channel high-side driver IC designed for automotive and industrial load control, featuring 160 mΩ R_DS(on) per channel, 5 A continuous output current, 36 V operating supply voltage, and integrated open-load detection in both on- and off-states. It drives grounded loads in body electronics, lighting, and HVAC systems with loss-of-ground protection and reverse-battery immunity.

For engineers reviewing the VNQ810PEP-E datasheet, VNQ810PEP-E pinout, VNQ810PEP-E application, or VNQ810PEP-E equivalent, this page delivers verified electrical specs, thermal behavior under real PCB conditions, diagnostic timing thresholds, and validated alternative parts for functional substitution in 12 V/24 V vehicle networks.

Technical Context

The device implements four independent VIPower M0-3 high-side switches with active current limiting, thermal shutdown at 150–200 °C, and automatic restart. Each channel includes CMOS-compatible inputs, open-drain status outputs, and dual-mode open-load detection-using output current monitoring during on-state and output voltage thresholding (1.5–3.5 V) during off-state.

Protection logic integrates undervoltage (4 V typ.) and overvoltage (36 V) shutdown, loss-of-ground detection via GND pin disconnection sensing, and VCC clamp for ISO 7637 transient immunity. The PowerSSO-24 package enables 66 W power dissipation per island with R_thj-case = 1.9 °C/W.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	160 mΩ max per channel at 25°C - ensures low conduction loss and <1 W dissipation at 5 A load.
I_OUT	5 A continuous per channel - supports high-current solenoids, lamps, and actuators without external heatsinking.
V_CC	5.5–36 V operating range - compatible with 12 V and 24 V automotive battery systems including cold-crank down to 5.5 V.
Open-load detection	On-state: 20–80 mA threshold; Off-state: 1.5–3.5 V threshold - enables reliable fault reporting without external circuitry.
Thermal shutdown	150–200 °C trip range with 135 °C reset and 7–15 °C hysteresis - prevents latch-up and allows safe recovery after overload.
Status output	Open-drain, 0.5 V max low-level voltage at 1.6 mA - directly interfaces with 3.3 V/5 V MCU GPIOs for real-time diagnostics.
ISO 7637-2	Class C compliance for pulses 1–4, Class E for pulse 5 - withstands load-dump transients up to +86.5 V for 400 ms.

Pinout & Package

Delivered in PowerSSO-24 package (24-pin exposed-pad surface-mount), with integrated VCC-connected thermal tab for enhanced heat dissipation. Pin mapping validated per STMicroelectronics Doc ID 10872 Rev 8 Figure 2 and Table 2.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Power supply input	36 V max DC supply; internal clamp protects against ISO 7637 pulse 1/2/3a/3b; connects to thermal pad.
GND	Ground reference	Loss-of-ground detection enabled; disconnect triggers immediate channel disable and status flag assertion.
IN1–IN4	Digital input control	CMOS-compatible (V_IL ≤ 1.25 V, V_IH ≥ 3.25 V); 0.5 V hysteresis prevents noise-induced switching.
OUT1–OUT4	High-side switched output	Drives grounded loads; features V_demag clamp (V_CC − 41 V) for inductive turn-off energy suppression.
STATUS1–STATUS4	Fault reporting output	Open-drain status per channel; pulled low during overtemperature, overcurrent, open-load, or UV/OV events.
N.C.	No-connect terminal	Not internally bonded; must remain unconnected per datasheet Table 2.

Key Features

Feature	Design Value
Reverse battery protection	Withstands −0.3 V V_CC and −200 mA I_GND; eliminates need for external series diode in battery-reverse scenarios.
Off-state open-load detection	Detects V_OUT > 2.5 V (typ.) when IN = 0 - identifies broken-wire faults before activation, critical for safety-critical lighting.
Very low standby current	20 µA max at 13 V V_CC - meets automotive quiescent current requirements for always-on modules.
Active current limitation	7.5 A typ. I_LIM at 13 V with thermal foldback - limits peak fault current while enabling controlled restart after cooling.
Shorted-load protection	Combines current limit + thermal shutdown + status flag - prevents destruction during sustained short-circuit at V_BAT.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
VNQ830PEP-E	Same PowerSSO-24 package; 160 mΩ R_DS(on), but rated for 5 A per channel with identical protection set.	Identical pinout and function; differs only in ordering code - direct replacement with no design change required.	Select when sourcing new production lots; VNQ830PEP-E supersedes VNQ810PEP-E in ST's active portfolio.
TPS4H160-Q1	4-channel 160 mΩ high-side driver; 40 V abs max; includes SPI diagnostics and programmable current limit (3–10 A).	Requires SPI interface and external pull-ups; offers finer diagnostic granularity but adds MCU firmware overhead.	Choose for next-gen designs needing configurable protection thresholds and fault logging via serial interface.

Compared with VNQ810PEP-E, VNQ830PEP-E provides identical electrical and thermal performance with updated part marking, while TPS4H160-Q1 trades simplicity for programmability - making the former ideal for drop-in replacement and the latter suited for systems requiring adaptive current limiting.

FAQ

What is the maximum allowable V_CC voltage for continuous operation?

The VNQ810PEP-E supports continuous operation up to 36 V V_CC, with absolute maximum rating of 41 V. Operation above 36 V triggers overvoltage shutdown to protect internal circuitry. This rating aligns with ISO 16750-2 automotive electrical load requirements for 24 V systems.

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

During off-state (IN = 0), the device applies a small test current to the output and monitors resulting voltage. If V_OUT exceeds 2.5 V (typ.), it indicates an open circuit (e.g., broken wire), triggering STATUS pin assertion. No external resistor or comparator is needed - the function is fully integrated and calibrated.

Can VNQ810PEP-E drive inductive loads like fuel injectors or relays?

Yes - the device includes active V_demag clamping (V_CC − 41 V) and supports demagnetization energy up to 22 mJ at 13.5 V. Its 5 A continuous rating and thermal foldback enable safe driving of automotive relays and solenoids, provided PCB copper area meets minimum 0.5 cm² per channel for thermal management.

Is the PowerSSO-24 package RoHS-compliant and lead-free?

Yes - the VNQ810PEP-E uses ST's ECOPACK® PowerSSO-24 package, certified RoHS-compliant and lead-free per EU Directive 2002/95/EC. The package employs matte tin plating and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) for standard SMT assembly.
