Product details
Overview
VN820PT13TR from STMicroelectronics is a high-side power switch IC designed for automotive and industrial load driving with ground-referenced loads. It features 40 mΩ RDS(on), 9 A continuous output current, 36 V maximum supply voltage, on/off-state open-load detection, and integrated short-circuit, overtemperature, undervoltage, overvoltage, reverse-battery, and loss-of-ground protection. It is used in body control modules for driving lamps, solenoids, and relays.
For engineers reviewing the VN820PT13TR datasheet, VN820PT13TR pinout, VN820PT13TR application, or VN820PT13TR equivalent, this device delivers robust fault diagnostics, CMOS-compatible input logic, ultra-low standby current (<3.5 µA), and ISO 7637-2 pulse-compliant transient immunity-critical for 12 V/24 V automotive power distribution systems.
Technical Context
The VN820PT13TR implements a monolithic VIPower M0-3 process high-side driver with active current limiting (9–20 A), thermal shutdown at 150–200 °C with 135 °C reset hysteresis, and dual-mode open-load detection: on-state via output current threshold (70–300 mA) and off-state via external pull-up–enabled voltage threshold (1.5–3.5 V). Its status pin provides real-time fault reporting with programmable delay (20 µs overload, 1000 µs off-state OL).
It integrates active VCC clamping for low-energy transients (ISO 7637 Pulse 1/2/3a/3b/4/5 Class C), reverse-battery protection via external ground-network solutions, and demagnetization clamp voltage (VCC−41 to VCC−55 V) for inductive load turn-off. Input logic is CMOS-compatible with 1.25 V low-level and 3.25 V high-level thresholds and 0.5 V hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 40 mΩ typical at IOUT = 3 A, Tj = 25 °C - enables <1 W conduction loss at 9 A, reducing heatsink requirements |
| IOUT Continuous | 9 A - supports high-current automotive loads like headlamps and fuel pumps without external current sharing |
| VCC 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 | On-state: 70–300 mA threshold; Off-state: 1.5–3.5 V threshold with external pull-up - enables diagnostics without added sensors |
| Thermal Shutdown | 150–200 °C trip, 135 °C reset - prevents latch-up during sustained overload while allowing safe auto-recovery |
| Standby Current | ≤3.5 µA at VCC = 13 V, Tj = 25 °C - meets automotive quiescent current requirements for always-on modules |
| ISO 7637-2 Immunity | Pulse 1–5 Class C compliance - survives automotive transients without external TVS or clamping diodes |
Pinout & Package
Package: PPAK (Power Package) - thermally enhanced surface-mount package with exposed drain pad for low Rthj-case (1.9 °C/W) and optimized PCB copper area (0.44 cm² minimum) for automotive under-hood thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | OUTPUT | High-side switched output terminals - paralleled internally to deliver 9 A total; connected directly to load anode |
| 9 | GND | Power ground reference - must be connected to chassis or battery negative; disconnect triggers automatic shutdown |
| 10 | INPUT | CMOS-compatible digital input - 1.25 V / 3.25 V thresholds with 0.5 V hysteresis; drives internal logic driver |
| 11 | STATUS | Open-drain diagnostic output - pulled low during faults (overload, OL, UV/OV, OT); requires external pull-up |
| 12 | VCC | Main supply input - rated 5.5–36 V DC; includes active clamp for ISO 7637 transients up to ±100 V |
Key Features
| Feature | Design Value |
|---|---|
| On/Off-State Open-Load Detection | Enables full-cycle load integrity verification - no need for separate sense resistors or microcontroller ADC sampling |
| Integrated Reverse-Battery Protection Support | Allows use of external ground-line resistor (RGND ≤ 600 mV/IS(on)max) or diode network - eliminates need for costly external MOSFETs |
| Active VCC Clamp + Thermal Auto-Restart | Withstands ISO 7637 pulses without external components and recovers automatically after transient-induced shutdown |
| Status Pin Fault Encoding | Single-pin reporting of 6 fault types (OL-on, OL-off, OV, UV, OT, GND-loss) with configurable timing delays |
| Ultra-Low Standby Current | <3.5 µA ensures compliance with automotive "parking mode" current budgets (<100 µA per module) |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN250 | Lower current rating (3.5 A), integrated current sense, no off-state open-load detection | Better suited for compact motor drivers; lacks full automotive diagnostic coverage | Select when current sensing is required and diagnostic depth is secondary to size/cost |
| INFINEON BTS724G | Higher RDS(on) (60 mΩ), identical 9 A rating, same PPAK package, but no reverse-battery support | Requires external reverse-polarity protection; less robust in battery-reversal scenarios | Select when ISO 7637 immunity and reverse-battery tolerance are not mandatory |
Compared with STSPIN250 and BTS724G, the VN820PT13TR uniquely combines full-cycle open-load detection, reverse-battery compatibility, and sub-4 µA standby current-making it optimal for safety-critical, always-on automotive modules where diagnostic completeness and ultra-low quiescent power are non-negotiable.

FAQ
What is the recommended external pull-up resistor value for off-state open-load detection?
For off-state open-load detection, ST recommends selecting RPU so that VOUT remains below 1.5 V when the load is connected (RPU < (VPU − 1.5 V)/IL(off2)), and above 3.5 V when disconnected. With VPU = 5 V and IL(off2) = −75 µA, RPU ≈ 47 kΩ satisfies both conditions and avoids false triggering across temperature.
Does VN820PT13TR require an external flyback diode for inductive loads?
No external flyback diode is required. The VN820PT13TR integrates an active demagnetization clamp that limits output voltage to VCC−41 V during turn-off, safely dissipating inductive energy. This feature eliminates external diodes in most automotive solenoid and relay applications, reducing board space and cost.
How does the device respond to loss of ground connection?
Upon loss of ground (GND pin disconnection), the VN820PT13TR immediately disables the output and pulls the STATUS pin low within microseconds. This behavior is hardwired into the VIPower M0-3 silicon and does not rely on software or external supervision-ensuring fail-safe shutdown even if the microcontroller is unresponsive.
Can VN820PT13TR be used in 24 V commercial vehicle systems?
Yes. With a 36 V absolute maximum VCC rating, 41 V clamp capability, and full ISO 7637-2 Pulse 5 (86.5 V, 400 ms) Class C immunity, the VN820PT13TR is qualified for 24 V commercial vehicle applications including trucks, buses, and agricultural machinery operating across wide battery voltage excursions and severe transient environments.
