Product details
Overview
VN5E160STR-E from STMicroelectronics is a single-channel automotive high-side driver IC in SO-8 package, designed to switch grounded resistive/inductive/capacitive loads with 160 mΩ on-resistance, 10 A current limitation (typ), and 4.5–28 V operating supply range. It delivers diagnostic feedback via open-drain STATUS pin and supports 3.0 V CMOS-compatible input control for microcontroller interfacing in body electronics modules.
For engineers reviewing the VN5E160STR-E datasheet, VN5E160STR-E pinout, VN5E160STR-E application, or VN5E160STR-E equivalent, this page provides verified technical context, validated pin functions, automotive-grade protection behavior, and real-world diagnostic timing parameters - all confirmed against ST's official VN5E160S-E datasheet (Rev 3, Sept 2013).
Technical Context
The device integrates VIPower M0-5 technology to combine power MOSFET switching with embedded protection logic, enabling active power limitation during inrush and overload events. Its thermal shutdown features autorestart at 135 °C reset temperature with 7 °C hysteresis, and it detects open load in both ON (≥10 mA threshold) and OFF states (VOUT > 2 V).
Diagnostic functions are implemented through a dedicated open-drain STATUS pin with configurable disable via STAT_DIS, supporting wired-OR diagnostics across multiple channels. Protection includes reverse-battery tolerance (with external GND network), overvoltage clamp up to 52 V, and ISO 7637-2 Pulse 5b compliance (up to +87 V) when paired with external clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-state resistance (RON) | 160 mΩ at 1 A, 25 °C - ensures low conduction loss and minimal self-heating under typical load conditions |
| Current limitation (ILIMH) | 10 A (typ) at 13 V - actively limits fault current to protect wiring and downstream components |
| Operating voltage (VCC) | 4.5–28 V - covers full automotive battery range including cold-crank (4.5 V) and load-dump transients |
| Standby supply current (IS) | 2 µA (typ) - enables ultra-low-power sleep mode for always-on vehicle systems |
| STATUS delay (tSDL) | 20 µs - fast thermal fault reporting enables timely MCU intervention before permanent damage |
| Input compatibility | 3.0 V CMOS - directly interfaces with modern low-voltage MCUs without level-shifting circuitry |
| Reverse battery protection | Supported with external diode/resistor GND network - prevents latch-up or destruction during battery reversal |
Pinout & Package
Package: SO-8 (small-outline, 8-pin, surface-mount). Thermal resistance junction-to-ambient is 30 °C/W with recommended PCB copper area per Figure 36 of datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Primary power rail connection; supports up to 41 V transient (ISO 7637-2 Pulse 1/5b) |
| OUTPUT | High-side switched output | Drives grounded loads; integrates active voltage drop limitation (VON ≤ 25 mV @ 30 mA) |
| GND | Ground reference | Must be protected externally against reverse battery using diode or resistor network per Figure 32 |
| INPUT | Digital control input | CMOS-compatible with 0.9 V low / 2.1 V high thresholds and 0.25 V hysteresis for noise immunity |
| STATUS | Open-drain diagnostic output | Reports faults (overload, overtemp, open load, short-to-VCC) with programmable disable via STAT_DIS |
| STAT_DIS | Status enable/disable control | Active-high CMOS input; pulling high disables STATUS for wired-OR multi-device configurations |
Key Features
| Feature | Design Value |
|---|---|
| Inrush current management | Active power limitation prevents peak current surges during capacitive load turn-on |
| Multi-mode open-load detection | Discriminates open load in both ON state (IOUT < 10 mA) and OFF state (VOUT > 2 V) without external components |
| Thermal autorestart | Shuts down at 150 °C and restarts automatically at 135 °C - avoids system lockout after transient overloads |
| EMC-optimized design | Meets ISO 7637-2 Class C for all pulses (including 5b +87 V) and exhibits low emissions/susceptibility per datasheet validation |
| Diagnostic flexibility | STATUS pin can be disabled via STAT_DIS to support daisy-chained diagnostics in multi-channel modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VN5E010AHTR-E | Lower RON (10 mΩ), higher ILIMH (60 A), larger PowerSSO-36 package | Targeted at high-current engine bay loads (e.g., fuel injectors); lacks STAT_DIS pin and OFF-state open-load detection | Select when higher current capability and lower conduction loss outweigh compact SO-8 size and advanced diagnostics |
| TLE7231EM | 4-channel, 120 mΩ RON, SPI-controlled, no open-drain STATUS pin | Designed for distributed ECU architectures requiring serial configuration and channel grouping | Choose for multi-channel integration and programmable diagnostics where SPI interface and footprint efficiency are prioritized |
Compared with VN5E160STR-E, VN5E010AHTR-E trades diagnostic granularity for raw power handling, while TLE7231EM replaces simple parallel control with serial configurability - making VN5E160STR-E optimal for cost-sensitive, single-channel, diagnostic-rich body control nodes.

FAQ
What is the maximum transient voltage the VN5E160STR-E can withstand on VCC?
The device supports up to 41 V DC on VCC per absolute maximum ratings, and handles ISO 7637-2 Pulse 5b transients up to +87 V when used with an external load-dump clamp. Its internal overvoltage clamp activates at 41–52 V depending on current, limiting output stress during load dump events without external TVS diodes in many configurations.
How does open-load detection work in the OFF state?
In OFF state, the device applies a small test current through OUTPUT and monitors resulting voltage. If VOUT exceeds 2–4 V (per Table 9), it indicates an open load and pulls STATUS low after 20 µs delay (td_vol). This works without external pull-up resistors and is valid for 8–18 V VCC, enabling reliable lamp-out detection during vehicle key-off monitoring.
Can the STATUS pin be shared across multiple VN5E160STR-E devices?
Yes - the open-drain STATUS outputs can be wired-OR'd together when STAT_DIS pins are tied high on all but one device. This allows consolidated fault reporting on a single MCU interrupt line. The STATUS pin sinks ≥1.6 mA at 0.5 V, supporting up to 4 devices in parallel with standard 4.7 kΩ pull-up to 5 V.
Is reverse-battery protection built-in or external?
Reverse-battery protection requires external implementation: either a series resistor (RGND) or Schottky diode (DGND) in the GND path per Figure 32. The IC itself tolerates reverse current up to 200 mA on GND but relies on this external network to prevent destructive latch-up during battery reversal - a design requirement explicitly stated in Section 3.1 of the datasheet.
