Product details

Overview

VN800STR-E from STMicroelectronics is a monolithic high-side driver IC fabricated in VIPower M0-3 technology, designed to drive grounded loads in industrial control systems. It features 135 mΩ on-state resistance, 0.7 A continuous output current, 36 V supply voltage rating, thermal shutdown, and reverse-battery protection. It is used in programmable logic controller (PLC) I/O modules compliant with IEC 61131-2.

For engineers reviewing the VN800STR-E datasheet, VN800STR-E pinout, VN800STR-E application, or VN800STR-E equivalent, key selection criteria include its active current limitation (0.7–2 A), under-voltage/over-voltage shutdown thresholds (4 V / 36 V), status pin diagnostics, and SO-8 package thermal performance (R_thj-amb = 93°C/W on 0.5 cm² copper).

Technical Context

The VN800STR-E integrates a protected power MOSFET with CMOS-compatible input logic, internal VCC clamp for ISO 7637 transient immunity, and loss-of-ground detection that forces automatic shutdown. Its status pin provides real-time fault reporting (over-temperature, over-current, under-voltage, over-voltage) via open-drain output with 0.5 V low-level voltage at 1.6 mA sink current.

Protection architecture combines active current limiting (adjustable via external load impedance), thermal shutdown at 150–200°C with 135°C reset hysteresis, and output clamping during inductive turn-off (V_demag = V_CC − 47 to −57 V). Input hysteresis (0.5 V) ensures noise-immune switching in harsh industrial environments.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	135 mΩ max at 0.5 A, 25°C - enables low conduction loss and minimal self-heating in 24 V DC control applications
I_OUT	0.7 A continuous - supports solenoid, relay, and LED load driving without external heatsinking
V_CC Range	5.5–36 V - accommodates wide industrial supply rails including 12 V, 24 V, and 30 V nominal systems
Current Limit	0.7–2 A typical - dynamically limits fault current to protect wiring and upstream power supplies
Shutdown Temp	150–200°C junction - thermal cutoff prevents catastrophic failure during sustained overload
Status Pin V_OL	0.5 V at 1.6 mA - ensures reliable low-level assertion for microcontroller GPIO fault detection
Input Hysteresis	0.5 V - rejects EMI-induced glitches on control lines in electrically noisy factory environments

Pinout & Package

Package: SO-8 (Small Outline, 8-lead, ECOPACK® compliant). Exposed pad thermally connected to GND for enhanced heat dissipation.

Pin/Terminal	Circuit Role	Design Meaning
1 (INPUT)	CMOS logic input	Accepts 3.25 V high / 1.25 V low; 0.5 V hysteresis prevents chatter during slow-rising control signals
2 (GND)	Power ground reference	Primary return path; loss-of-ground detection triggers immediate shutdown
3 (OUTPUT)	High-side switched output	Drives load between OUTPUT and system ground; supports inductive demagnetization energy up to 121 mJ
4 (STATUS)	Open-drain diagnostic output	Pulls low on fault (over-temp, over-current, UV/OV); requires external pull-up for MCU interface
5 (VCC)	Power supply input	Internally clamped to 41 V max; withstands ISO 7637-2 pulse 1/2/5a transients
6–8 (NC)	No connect	Not internally bonded; must be left floating or tied to GND per Table 2 of datasheet

Key Features

Feature	Design Value
Reverse battery protection	Integrated clamp allows operation with −0.3 V V_CC; external RGND/DGND network enables full reverse-polarity survivability
Loss-of-ground detection	Automatic shutdown when GND pin disconnects - prevents uncontrolled load activation and system damage
Active current limitation	Adjustable trip point (0.7–2 A) via load impedance - eliminates need for external fusing in most I/O designs
Diagnostic status pin	Single-wire fault signaling (over-temp, short-circuit, UV/OV) - reduces MCU GPIO count and simplifies firmware diagnostics
VIPower M0-3 process	Monolithic integration of logic, protection, and power stage - eliminates discrete gate drivers and sense resistors

Automated Test Equipment (ATE) Load Switching

Factory Floor Lighting Control

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPS1021HTR	Higher R_DS(on) (220 mΩ), lower I_OUT (0.5 A), no reverse-battery protection	Limited to low-power loads; requires external reverse-polarity circuitry	Select when cost sensitivity outweighs robustness requirements and load current ≤0.5 A
TPS27081AQPWPRQ1	Lower voltage rating (20 V max), no status pin, automotive AEC-Q100 qualified	Suitable only for 12 V automotive body electronics; lacks industrial diagnostics	Choose only for automotive-grade 12 V systems where ISO 16750-2 compliance is mandatory

Compared with VN800STR-E, IPS1021HTR trades protection and current capability for lower cost, while TPS27081AQPWPRQ1 sacrifices industrial voltage range and diagnostics for automotive qualification - neither matches the VN800STR-E's combination of 36 V operation, integrated status feedback, and reverse-battery resilience in IEC 61131-2 environments.

FAQ

What is the maximum inductive load energy the VN800STR-E can safely demagnetize?

The VN800STR-E (SO-8 variant) supports up to 121 mJ of switching energy with L = 77.5 mH, RL = 0 Ω, V_BAT = 13.5 V, and T_j,start = 150°C. This value assumes proper PCB copper area (0.5 cm²) and accounts for internal V_demag clamping at V_CC − 47 V. Exceeding this limit risks avalanche failure.

How does the loss-of-ground protection function, and what is its response time?

Loss-of-ground detection monitors GND pin continuity via internal sensing circuitry. When GND disconnects, the device immediately disables the output and asserts STATUS low within 20 µs (t_SDL). This action prevents uncontrolled load activation and protects downstream circuitry from floating ground hazards.

Can the VN800STR-E drive capacitive loads, and what are the limitations?

The VN800STR-E is not characterized for direct capacitive load driving. Its output stage is optimized for resistive and inductive loads. Driving large capacitive loads (>100 nF) may cause excessive peak current during turn-on, triggering current limiting or thermal shutdown. External series resistance is recommended for such cases.

Is the STATUS pin compatible with 3.3 V microcontrollers without level shifting?

Yes. The STATUS pin is open-drain with V_OL ≤ 0.5 V at 1.6 mA sink current, fully compatible with 3.3 V GPIO inputs. An external pull-up resistor (typically 4.7–10 kΩ) to 3.3 V is required. No level shifter is needed, provided the MCU input high threshold is ≤3.0 V.
