Product details
Overview
VN800PSTR-61-E from STMicroelectronics is an automotive-grade high-side driver IC built on VIPower™ M0-3 technology, designed to switch grounded loads in industrial and automotive control systems. It delivers 0.7 A continuous output current, features 135 mΩ typical RDS(on), operates up to 36 V VCC, and integrates thermal shutdown, undervoltage/overvoltage protection, and reverse battery immunity - making it suitable for IEC 61131-compliant programmable logic controllers.
For engineers reviewing the VN800PSTR-61-E datasheet, VN800PSTR-61-E pinout, VN800PSTR-61-E application, or VN800PSTR-61-E equivalent, this device is evaluated for robust load switching in harsh environments requiring diagnostic feedback (via STATUS pin), low standby current (<10 µA), and AEC-Q100-aligned reliability - especially where ground-referenced solenoids, valves, or lamps demand fault-aware power control.
Technical Context
The VN800PSTR-61-E implements a monolithic high-side switch with CMOS-compatible input logic, active VCC clamping for transient suppression (ISO 7637-2 Pulse 1–5 compliant), and integrated current limiting that dynamically adjusts with junction temperature. Its status pin provides open-drain diagnostic output indicating overtemperature, overcurrent, or supply faults.
Protection architecture includes thermal shutdown at 150–200 °C with 15 °C hysteresis, undervoltage lockout (4 V typ.) and overvoltage shutdown (36 V typ.), plus reverse-battery tolerance via external GND network design. The device automatically disables upon GND pin disconnection, ensuring fail-safe behavior in wiring fault scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 5.5 V to 36 V - supports wide automotive battery range including cold-crank (5.5 V) and load-dump (36 V) conditions. |
| RDS(on) | 135 mΩ (typ.) at IOUT = 0.5 A, Tj = 25 °C - enables <1 W conduction loss at 0.7 A, reducing heatsink requirements. |
| IOUT Continuous | 0.7 A - rated for sustained switching of solenoids, relays, and indicator lamps without derating below 100 °C case temperature. |
| Standby Current | 10 µA (max.) at VCC = 24 V - meets ultra-low-power requirements for always-on vehicle modules. |
| Turn-off Delay | 40 µs (typ.) - ensures fast de-energization of inductive loads to limit demagnetization energy and voltage spikes. |
| Status Pin Logic | Open-drain, VSTAT(L) ≤ 0.5 V at ISTAT = 1.6 mA - directly interfaces with 3.3 V/5 V microcontroller GPIO for real-time fault reporting. |
| Thermal Shutdown | Triggers at 150 °C (min.), resets at 135 °C - provides self-protecting operation during sustained overload or poor PCB thermal layout. |
Pinout & Package
Package: SO-8 (Small Outline, 150 mil width), RoHS-compliant, ECOPACK® certified, with exposed pad for enhanced thermal dissipation (Rthj-amb = 82 °C/W with 2 cm² copper).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | CMOS-compatible digital input | Accepts 3.25 V high / 1.25 V low thresholds with 0.5 V hysteresis; drives internal gate with <200 µA max input current. |
| 2 (GND) | Power and signal reference ground | Must be connected to system ground; device disables if disconnected - critical for reverse-battery fault detection. |
| 3 (OUT) | High-side switched output | Drives load between VCC and load ground; features active clamp during turn-off to limit VOUT overshoot. |
| 4 (VCC) | Main supply input | Supplies internal circuitry and gate drive; includes active clamp protecting against low-energy transients per ISO 7637. |
| 5 (NC) | No connect | Internally unused; must remain unconnected per datasheet guidance (Table 2). |
| 6 (STATUS) | Diagnostic open-drain output | Pulls low during overtemperature, overcurrent, undervoltage, or overvoltage - enables single-wire fault monitoring. |
| 7 (NC) | No connect | Internally unused; must remain unconnected per datasheet guidance (Table 2). |
| 8 (VCC) | Secondary supply connection | Parallel-connected to Pin 4 to reduce package inductance and improve transient immunity on VCC rail. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 (−40 °C to +125 °C ambient), validated for 15-year vehicle life under cyclic stress. |
| Reverse battery protection | Supported via external GND network (resistor or diode); prevents damage when battery polarity is inverted. |
| Integrated diagnostics | Single-pin STATUS output reports four fault types (thermal, current, UV/OV) with <20 µs delay after fault onset. |
| Low-energy transient immunity | Withstands ISO 7637-2 pulses 1–5 (including −100 V/2 ms, +100 V/0.2 ms) without latch-up or parameter shift. |
| Load-disconnect safety | Automatic shutdown when GND pin is open - eliminates risk of uncontrolled load activation due to wiring faults. |
Applications
| Industrial PLC Output Module | Automotive Body Control Unit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN250TR | Lower RDS(on) (80 mΩ), but only 0.5 A continuous; no STATUS pin; lacks undervoltage/overvoltage detection. | Suitable for cost-sensitive, non-diagnostic 24 V fan or pump drives where thermal margin is ample. | Select when diagnostic reporting is unnecessary and board space is constrained (3 × 3 mm QFN vs. SO-8). |
| TPS27081AQPWPRQ1 | Higher IOUT (1.5 A), integrated charge pump, but no reverse-battery support and only basic thermal shutdown (no hysteresis or reset temp spec). | Better for high-current automotive lighting, but requires external reverse-polarity protection and separate fault monitoring. | Prefer when driving >1 A resistive loads and system-level diagnostics are handled externally via MCU ADC. |
Compared with STSPIN250TR and TPS27081AQPWPRQ1, the VN800PSTR-61-E uniquely combines AEC-Q100 qualification, full diagnostic coverage (UV/OV/OT/OC), reverse-battery readiness, and SO-8 manufacturability - making it the only choice for IEC 61131-compliant industrial controllers requiring zero-additional-component fault awareness.

FAQ
What is the maximum inductive load energy the VN800PSTR-61-E can safely demagnetize?
The device supports up to 121 mJ of switching energy (EMAX) under defined test conditions (L = 77.5 mH, Vbat = 13.5 V, IL = 1.5 A, Tjstart = 150 °C). This value is validated per Figure 7 and Table 5 in the datasheet and assumes proper PCB copper area (≥2 cm²) for thermal management. Exceeding this energy risks thermal runaway during turn-off.
Can the STATUS pin drive an LED directly without a current-limiting resistor?
No. The STATUS pin is an open-drain output rated for 1.6 mA sink current at ≤0.5 V. Driving an LED directly would exceed its absolute maximum rating and cause undefined behavior. A series resistor (e.g., 1 kΩ for 3.3 V supply) is mandatory to limit current to ≤1 mA and ensure reliable low-state voltage.
Does the VN800PSTR-61-E require external pull-up resistors on IN or STATUS pins?
Yes. The IN pin has no internal pull-up; a 10 kΩ external pull-up to VCC is required for default-high logic if floating inputs are unacceptable. The STATUS pin also requires an external pull-up (typically 4.7–10 kΩ to VCC) to generate a valid high-level signal during normal operation.
How does the device behave during ground pin disconnection?
When the GND pin is disconnected, the internal ground-sense circuit detects loss of reference and forces the output into immediate high-impedance state within <10 µs. This prevents uncontrolled load activation and is confirmed in Section 1 (Description) and Figure 1 block diagram - a key safety feature for wiring fault resilience.
