Product details

Overview

VND810PTR-E from STMicroelectronics is a double-channel high-side driver IC designed for automotive and industrial load switching, with 160 mΩ on-state resistance per channel, 3.5 A continuous output current, 36 V supply voltage rating, CMOS-compatible inputs, and integrated open-load detection in both on- and off-states. It drives grounded loads in body control modules, lighting systems, and HVAC actuators.

For engineers reviewing the VND810PTR-E datasheet, VND810PTR-E pinout, VND810PTR-E application, or VND810PTR-E equivalent, key selection criteria include thermal shutdown behavior, undervoltage/overvoltage clamp thresholds, status pin diagnostic logic, and ISO 7637-2 transient immunity compliance.

Technical Context

The device integrates two independent VIPower™ M0-3 high-side switches with active VCC clamping for low-energy spike suppression (ISO 7637-2 Pulse 1, 2, 3a/b, 4, 5 compliant), programmable current limitation (3.5–7.5 A), and thermal shutdown at 150–200 °C with 135 °C reset hysteresis.

Each channel features dual-mode open-load detection: on-state current threshold (20–80 mA) and off-state voltage threshold (1.5–3.5 V), plus output stuck-to-VCC detection during off-state, reverse battery protection via internal GND network, and electrostatic discharge robustness (4 kV HBM on INPUT/STATUS, 5 kV on OUTPUT/VCC).

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	160 mΩ per channel at I_OUT = 1 A, T_j = 25 °C - enables low conduction loss and minimal self-heating under full load
I_OUT (continuous)	3.5 A per channel - supports driving solenoids, relays, and LED arrays without external heatsinking in typical automotive ambient
V_CC range	5.5–36 V - accommodates 12 V and 24 V vehicle electrical systems including cold-crank and load-dump transients
Open-load detection	On-state: 20–80 mA threshold; Off-state: 1.5–3.5 V threshold - provides reliable fault reporting without external sensing components
Thermal shutdown	150–200 °C trip, 135 °C reset - prevents permanent damage during sustained overload while enabling automatic recovery
Undervoltage lockout	3–5.5 V - disables outputs below safe MCU logic level to prevent erratic switching during brown-out
ISO 7637-2 immunity	Pulse 1–5 Class C performance - ensures functional integrity during automotive electrical disturbances without external TVS

Pinout & Package

SO-16 surface-mount package with exposed thermal pad (pin 9 connected to GND for thermal and electrical reference). Pin numbering follows standard SO-16 top-view convention.

Pin/Terminal	Circuit Role	Design Meaning
1, 8, 9, 16	V_CC	Power supply input with active clamp diode to ground - absorbs low-energy transients per ISO 7637-2 Pulse 1/3a
2, 7	GND	Ground reference for logic, power, and thermal dissipation - pin 9 is dedicated thermal pad tied to GND
3, 6	INPUT1 / INPUT2	CMOS-compatible digital inputs - 1.25 V low, 3.25 V high thresholds with 0.5 V hysteresis for noise immunity
4, 5	OUTPUT1 / OUTPUT2	High-side switched outputs - each drives one side of load; internally limited to 3.5 A and protected against short-to-V_CC
10, 13	STATUS1 / STATUS2	Open-drain diagnostic outputs - pulled low during overtemperature, undervoltage, overvoltage, open-load, or current limit
11, 14	N.C.	No-connect pins - must be left floating or tied to GND per Table 2; no internal connection
12, 15	V_CC (redundant)	Additional V_CC pins - improve current sharing and reduce package inductance for high-current paths

Key Features

Feature	Design Value
Automotive Grade AEC-Q100 qualified	Qualified per AEC-Q100 Rev H - validated for -40 °C to +150 °C operation in engine bay and chassis applications
Dual independent channel control	Separate INPUT/STATUS per channel - enables asynchronous switching and individual fault isolation in multi-load systems
Reverse battery protection	Internal GND network with resistor/diode options - eliminates need for external series diode or MOSFET in battery feed path
Load dump protection	V_CC clamp active up to 41 V - suppresses ISO 7637-2 Pulse 5a/b transients without external TVS diodes
Diagnostic status signaling	Single-pin open-drain output per channel - reports six fault conditions (open-load, overtemp, UV/OV, short-to-V_CC, current limit) with defined timing delays

Applications

Body Control Module (BCM)

LED Headlamp Driver

Use Scenario: Centralized switching of door locks, window lifts, and interior lighting in 12 V vehicle architectures.

IC Role / Device Role / Timing Role: High-side driver providing controlled power delivery with diagnostic feedback to microcontroller via STATUS pins.

Use Value: Eliminates discrete FETs and sense resistors; reduces BOM count by 40% versus discrete solutions while enabling real-time open-load detection during sleep mode.

Use Scenario: Driving high-brightness LED arrays in adaptive front-lighting systems (AFS) requiring PWM dimming and fault monitoring.

IC Role / Device Role / Timing Role: Constant-current-capable high-side switch with fast turn-on/turn-off (≤30 µs) and thermal foldback during overtemperature events.

Use Value: Maintains LED brightness stability across temperature; STATUS pin alerts MCU within 200 µs of open-circuit condition, preventing false DTCs.

HVAC Actuator Control

Engine Cooling Fan Interface

Use Scenario: Controlling DC motor-driven blend air doors and recirculation flaps in automotive HVAC units.

IC Role / Device Role / Timing Role: Dual-channel driver managing bidirectional motor control logic (via external H-bridge) with stall detection via off-state open-load sensing.

Use Value: Detects motor stall or broken linkage without current-sense amplifier; STATUS pin asserts within 1 ms of stalled condition at 12 V supply.

Use Scenario: Direct drive of brushless DC cooling fans in engine compartments subject to 150 °C ambient and load-dump transients.

IC Role / Device Role / Timing Role: Robust high-side interface between MCU and fan motor, with integrated overvoltage clamp and thermal shutdown.

Use Value: Survives repeated ISO 7637-2 Pulse 5 (86.5 V, 400 ms) events; automatic restart after thermal recovery avoids fan lock-up during peak engine load.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS27082LDR	Single-channel, 2.8 A max, 40 V abs max, no off-state open-load detection	Lacks dual-channel integration and diagnostic coverage - requires two devices and external comparators for equivalent functionality	Choose when board space allows discrete channel duplication and diagnostics are handled externally
BTS716G	Double-channel, 3.5 A, but only on-state open-load detection; no off-state or stuck-to-V_CC reporting	Reduced fault coverage - cannot detect disconnected load while powered off, increasing risk of undetected wiring faults	Acceptable where system-level diagnostics compensate for missing off-state detection capability

Compared with TPS27082LDR and BTS716G, the VND810PTR-E delivers complete per-channel diagnostics (on/off-state open-load, short-to-V_CC, thermal, UV/OV) in a single SO-16 package, reducing PCB area by 35% and eliminating external fault-sensing components required by alternatives.

FAQ

What is the maximum junction temperature before thermal shutdown activates?

Thermal shutdown triggers between 150 °C and 200 °C depending on process variation, with a guaranteed reset at 135 °C. The device enters automatic restart mode once junction temperature falls below the reset threshold, enabling recovery without MCU intervention after transient overload events.

Does the VND810PTR-E support PWM dimming of LED loads?

Yes - the device supports PWM frequencies up to 20 kHz with typical turn-on/turn-off delays of 30 µs each. Its controlled dV/dt (≤1 V/µs) minimizes EMI during switching, and status pin diagnostics remain fully functional during PWM operation without blanking periods.

How is reverse battery protection implemented without external components?

Reverse battery protection uses an internal GND network that routes reverse current through a dedicated path with built-in current limiting. Section 3.1 of the datasheet details two implementation options: a simple series resistor (RGND) or a diode (DGND) in the ground line - both leverage the IC's internal architecture to avoid external polarity protection FETs.

Can unused INPUT and STATUS pins be left floating?

No - unused INPUT pins must be tied to GND or V_CC to prevent unintended switching; unused STATUS pins may be left floating but are best pulled up externally for deterministic logic levels. Table 2 in the datasheet specifies recommended connections: N.C. pins should be left floating, while unused INPUT/STATUS require defined biasing.
