Product details

Overview

VN800PSTR-E from STMicroelectronics is an automotive-grade high-side driver IC built on VIPower™ M0-3 technology, designed to switch grounded resistive/inductive loads in industrial and automotive control systems. It delivers 0.7 A continuous output current, features 135 mΩ R_DS(on), operates up to 36 V V_CC, and integrates thermal shutdown, undervoltage/overvoltage protection, reverse battery immunity, and CMOS-compatible input logic.

For engineers reviewing the VN800PSTR-E datasheet, VN800PSTR-E pinout, VN800PSTR-E application, or VN800PSTR-E equivalent, this page provides verified functional context, SO-8 package layout, real-world load switching behavior, diagnostic status signaling, and validated alternatives for IEC 1131-compliant programmable controller designs.

Technical Context

The device implements a monolithic high-side power switch with active V_CC clamping for low-energy transient suppression and integrated current limiting (0.7–2 A) that works in tandem with thermal shutdown (trip at 150–200 °C) and automatic restart. Its status pin provides open-drain fault reporting with <0.5 V low-level output under 1.6 mA load.

Input logic features 0.5 V hysteresis, 1.25 V low-level threshold, and 3.25 V high-level threshold - compatible with standard 3.3 V/5 V microcontrollers. Protection functions include undervoltage lockout (4 V typ), overvoltage shutdown (42 V max), and demagnetization clamp (V_OUT ≤ V_CC − 47 V).

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	135 mΩ typical at 0.5 A, 25 °C - ensures <170 mW conduction loss at rated load
I_OUT Continuous	0.7 A - supports solenoids, relays, and LED arrays in 12/24 V systems
V_CC Range	5.5–36 V - covers automotive battery range including cold-crank (6 V) and load-dump (41 V abs max)
Standby Current	10 µA max at 24 V - enables ultra-low-power sleep mode in always-on controllers
Thermal Shutdown	150 °C trip, 135 °C reset - provides safe overload recovery without external circuitry
Status Pin Output	Open-drain, <0.5 V @ 1.6 mA - directly interfaces with MCU GPIO for fault diagnostics
Input Hysteresis	0.5 V - prevents noise-induced toggling during slow-rising control signals

Pinout & Package

Delivered in SO-8 package (ECOPACK® compliant, RoHS certified), the VN800PSTR-E uses a standard 8-pin surface-mount outline with exposed thermal pad (not electrically connected). Pin assignment follows ST's high-side driver convention optimized for PCB thermal management and EMI reduction.

Pin/Terminal	Circuit Role	Design Meaning
1 (IN)	CMOS-compatible digital input	Accepts 1.25–3.25 V logic-high; drives internal gate with hysteresis for noise immunity
2 (GND)	Power ground reference	Must be low-impedance connection; disconnect detection disables output automatically
3 (OUT)	High-side switched output	Drives load between OUT and GND; includes active clamp for inductive kickback
4 (V_CC)	Supply input with clamp diode	Internally clamped to ~42 V; absorbs ISO 7637-2 pulse 1/2/3a/3b transients
5 (STATUS)	Open-drain fault indicator	Pulled low during overtemperature, overcurrent, undervoltage, or overvoltage events
6–8 (NC)	No-connect terminals	Not internally bonded; left floating per ST recommendation for stability

Key Features

Feature	Design Value
Reverse Battery Protection	With external DGND diode or RGND resistor network - prevents damage during −12 V battery reversal
Active Overvoltage Clamp	V_CC clamped at 42 V max - eliminates need for external TVS in most 24 V automotive applications
Diagnostic Status Pin	Single-pin fault reporting for 4 distinct conditions - reduces MCU GPIO count and firmware complexity
Load Disconnection Detection	Automatic OFF-state when GND pin opens - prevents uncontrolled load activation in wiring fault scenarios
AEC-Q100 Qualified	Automotive Grade - qualified per AEC guidelines for under-hood and chassis-mounted control modules

Applications

Smart Power Distribution

Heating Element Control

Use Scenario: Replacing mechanical relays in centralized power distribution units for HVAC or lighting subsystems.

IC Role / Device Role / Timing Role: Solid-state switch with current limiting and thermal foldback - enables predictive maintenance via status pin monitoring.

Use Value: Reduces system size and acoustic noise; supports PWM dimming of resistive loads up to 0.7 A.

Use Scenario: Regulating ceramic heater elements in industrial ovens or medical devices requiring fail-safe shutdown.

IC Role / Device Role / Timing Role: High-side driver with automatic thermal shutdown and restart - prevents overheating without software intervention.

Use Value: Trip at 150 °C with 15 °C hysteresis ensures stable cycling; avoids thermal runaway in enclosed enclosures.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPS1025H	Higher 2.5 A rating, 40 mΩ R_DS(on), SPI interface, no STATUS pin	Requires MCU with SPI; lacks direct fault pin - needs firmware polling	Choose for higher current or digital configuration; avoid if simple GPIO fault reporting is required
TLE7231EM	0.5 A rating, 250 mΩ R_DS(on), integrated watchdog timer, same SO-8 footprint	Includes window watchdog for safety-critical ASIL-B systems; lower drive capability	Prefer for ISO 26262-compliant designs needing hardware watchdog; not suitable for >0.5 A loads

Compared with VN800PSTR-E, IPS1025H offers greater current headroom but removes the analog-friendly STATUS pin, while TLE7231EM adds functional safety features at the cost of reduced output capability - making VN800PSTR-E optimal for cost-sensitive, diagnostic-driven industrial controls where 0.7 A suffices.

FAQ

What is the maximum inductive load energy the VN800PSTR-E can safely demagnetize?

The device supports up to 121 mJ of switching energy (L = 77.5 mH, V_BAT = 13.5 V, I_L = 1.5 A, T_j,start = 150 °C), verified per ST's avalanche energy test circuit. This enables reliable turn-off of medium-inductance solenoids and relay coils without external snubbers in SO-8 layout with ≥2 cm² copper pour.

Does the VN800PSTR-E require external components for basic operation?

No external components are required for core switching functionality. However, ST recommends a 1 kΩ resistor in series with IN and STATUS pins when interfacing with MCUs exposed to battery transients, and either a ground-line diode (DGND) or resistor (RGND) for reverse-battery protection - both detailed in Section 3.1 of the datasheet.

How does the STATUS pin behave during undervoltage and overvoltage events?

The STATUS pin goes low during both undervoltage (V_CC < 4 V typ) and overvoltage (V_CC > 42 V max) conditions, as confirmed by Table 11's truth table. It remains low until V_CC returns to the valid 5.5–36 V operating range and internal circuitry resets - providing unambiguous fault indication without timing ambiguity.

Can the VN800PSTR-E drive capacitive loads such as MOSFET gates?

No - the VN800PSTR-E is not characterized or recommended for capacitive gate-driving applications. Its output stage is optimized for resistive/inductive loads up to 0.7 A. Driving MOSFET gates requires fast slew rates and low output impedance not specified in the datasheet; use dedicated gate drivers like ST's L9110S instead.
