Product details

Overview

VNQ830MTR-E from STMicroelectronics is a quad-channel high-side driver IC designed for automotive and industrial load switching applications, featuring 60 mΩ R_DS(on) per channel, 6 A continuous output current, 36 V supply voltage rating, and integrated open-load detection in both on/off states. It drives grounded loads such as solenoids, relays, and incandescent lamps in body control modules and power distribution units.

For engineers reviewing the VNQ830MTR-E datasheet, VNQ830MTR-E pinout, VNQ830MTR-E application, or VNQ830MTR-E equivalent, key selection considerations include its dual-island SO-28 thermal architecture, ISO 7637-2 transient immunity (Pulse 1–5), reverse battery protection, and status pin diagnostics with programmable external pull-up for off-state open-load detection.

Technical Context

The VNQ830MTR-E integrates two independent VND830M-E VIPower M0-3 monolithic chips in a single SO-28 "double island" package, enabling thermally isolated operation of two dual-channel islands. Each channel implements active current limiting, thermal shutdown with 150°C trip and 135°C reset, and dedicated status output with open-drain logic.

It supports CMOS-compatible inputs (VIH = 3.25 V, VIL = 1.25 V), detects undervoltage (VUSD = 4 V typ.) and overvoltage (VOV = 36 V) conditions, and provides loss-of-ground protection via internal ground pin monitoring. The device complies with ISO 7637-1 transient immunity up to Pulse 5 (+86.5 V, 400 ms).

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	60 mΩ max at I_OUT = 2 A, T_j = 25°C - enables low conduction loss for 12 V automotive loads up to 6 A
I_OUT Continuous	6 A per channel - supports driving high-current solenoids and heated mirrors without external heatsinking under defined PCB copper area
V_CC Range	5.5 V to 36 V - covers full automotive battery range including cold-crank (5.5 V) and load-dump (36 V)
Open-Load Detection	0.9 A threshold in ON state; 2.5 V threshold in OFF state - reliably identifies 5 W/12 V bulb failure and disconnected loads
Thermal Shutdown	150°C trip, 135°C reset with 15°C hysteresis - prevents permanent damage during sustained overload or short-circuit events
ISO 7637-1 Immunity	Pulse 1 (−100 V), Pulse 2 (+100 V), Pulse 3b (+100 V), Pulse 4 (−7 V), Pulse 5 (+86.5 V) - meets OEM EMC requirements without external clamping
Standby Current	12 µA max at V_CC = 13 V - minimizes battery drain in always-on vehicle modules

Pinout & Package

Package: SO-28 "Double Island" (two electrically and thermally isolated islands, each containing two channels), 35 µm Cu, 2 mm PCB thickness, 58 mm × 58 mm board area.

Pin/Terminal	Circuit Role	Design Meaning
1, 14, 15, 28	V_CC1,2 / V_CC3,4	Power supply pins for Island 1 (Ch1–Ch2) and Island 2 (Ch3–Ch4); each pair must be decoupled locally
2, 3, 16, 17	GND1,2 / GND3,4	Island-specific ground returns; separate routing prevents cross-talk and ensures accurate open-load sensing
4, 6, 19, 21	INPUT1–INPUT4	CMOS-compatible digital inputs; 1.25 V low / 3.25 V high thresholds with 0.5 V hysteresis for noise immunity
5, 7, 20, 22	OUTPUT1–OUTPUT4	High-side switched outputs; internally clamped to V_CC − 48 V during demagnetization of inductive loads
8, 9, 23, 24	STATUS1–STATUS4	Open-drain diagnostic outputs; pulled high externally to indicate normal operation or fault (e.g., open load, overtemp)
10–13, 25–27	N.C.	No-connect pins; must remain unconnected per datasheet Figure 3 - floating or grounded causes undefined behavior

Key Features

Feature	Design Value
Quad-channel high-side drive with dual-island isolation	Enables independent thermal management and fault containment: failure in Channel 1 does not affect Channel 3
On/off state open-load detection	Detects 5 W/12 V bulb disconnect in ON state (0.9 A threshold) and floating load in OFF state (2.5 V threshold with external pull-up)
Reverse battery protection	Withstands −13.5 V reverse supply without external diode; internal clamp limits reverse current to safe levels
Integrated ISO 7637-1 transient protection	Eliminates need for external TVS on V_CC for Pulses 1–5 - reduces BOM count and PCB area in body electronics
Status pin diagnostics with configurable timing	Programmable delay (t_DOL(off) = 1000 µs) and voltage thresholds allow robust fault discrimination in noisy automotive environments

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN840TR	Single-chip quad HSD with integrated SPI interface; 120 mΩ R_DS(on); no dual-island thermal separation	Lacks analog status pins; requires MCU firmware for diagnostics instead of direct GPIO monitoring	Choose when digital control and daisy-chain configuration outweigh need for analog fault reporting
BTS724G	Quad HSD in PG-DSO-28; 100 mΩ R_DS(on); no reverse battery protection; requires external V_CC TVS for Pulse 5	Higher conduction loss increases thermal stress on PCB; lacks integrated reverse-battery clamp	Choose only if cost sensitivity dominates and external protection can be added without compromising layout space

Compared with STSPIN840TR and BTS724G, the VNQ830MTR-E uniquely delivers dual-island thermal isolation, reverse-battery tolerance, and analog status outputs - making it optimal for safety-critical automotive body electronics where fault containment and analog diagnostic simplicity are mandatory.

FAQ

What is the maximum continuous output current per channel?

The VNQ830MTR-E supports 6 A continuous output current per channel under specified thermal conditions: SO-28 package mounted on FR-4 with 6 cm² copper per island, horizontal orientation, no forced airflow. Derating applies above 25°C ambient - see Figure 19 for R_DS(on) vs. T_case and Figure 19 for I_LIM vs. T_case.

How does off-state open-load detection work, and what external components are required?

Off-state open-load detection requires an external pull-up resistor (R_PU) between OUTPUT and a positive supply (e.g., +5 V). When the load is disconnected, leakage current (I_L(off2) ≤ 0 µA) pulls OUTPUT above 2.5 V, triggering STATUS low. R_PU must satisfy: R_PU < (V_PU − 3.5 V)/|I_L(off2)| and V_PU·R_L/(R_L + R_PU) < 1.2 V to avoid false detection with load connected.

Does the VNQ830MTR-E require external TVS diodes for ISO 7637-1 compliance?

No external TVS is required for ISO 7637-1 Pulse 1 through Pulse 5 compliance. The device integrates active V_CC clamping that limits transient energy absorption, achieving Class C performance (full functionality retained) for all pulses per Table 13. External clamping is only needed if system-level testing exceeds Pulse 5 severity or if additional margin is mandated by specific OEM standards.

Can unused INPUT and STATUS pins be left floating?

No. Unused INPUT and STATUS pins must remain unconnected - neither tied to V_CC, GND, nor pulled - as stated in Figure 3 and page 3 of the datasheet. Floating these pins is explicitly permitted and recommended; connecting them risks unintended activation, incorrect status reporting, or violation of absolute maximum ratings due to internal clamp structures.
