Product details
Overview
VND5E004ATR-E from STMicroelectronics is a dual-channel automotive-grade high-side power switch with 4 mΩ RON, integrated analog current sense per channel, and AEC-Q100 qualification. It drives 12 V grounded resistive/inductive/capacitive loads in engine control units, body electronics, and lighting modules, delivering precise load current monitoring (K0 = 12.13 kA/A typ), thermal shutdown with auto-restart, and reverse-battery protection.
For engineers reviewing the VND5E004ATR-E datasheet, VND5E004ATR-E pinout, VND5E004ATR-E application, or VND5E004ATR-E equivalent, this page provides verified technical context, diagnostic behavior under short-to-VCC and open-load conditions, current-sense accuracy across -40 °C to 150 °C, and validated alternatives for automotive power distribution designs.
Technical Context
The device implements two independent VIPower® M0-5 high-side switches with active power limitation for inrush and overload management, plus dedicated analog current sense outputs (CS1/CS2) delivering proportional ISENSE with ±5% full-scale error over temperature. Each channel features CMOS-compatible 3 V/5 V inputs with hysteresis, off-state open-load detection, and short-to-VCC diagnosis enabled via the DE pin.
Protection architecture includes undervoltage shutdown (VUSD = 4.5 V), overvoltage clamp (41–52 V), self-limiting fast thermal transients, and overtemperature shutdown at 150 °C with 7 °C hysteresis and auto-restart. The PQFN-12x12 package delivers Rthj-case = 0.35 °C/W for single-channel operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RON (per channel) | 4 mΩ max at 15 A, 25 °C - enables low conduction loss in 12 V automotive systems |
| ILIMH | 90 A typical short-circuit current limit - sustains brief overloads without latch-up |
| VCC operating range | 4.5 V to 28 V - supports cold-crank (4.5 V) and load-dump (28 V) conditions |
| Current sense ratio K0 | 12.13 kA/A typ at 5 A - allows accurate real-time load current reconstruction using external resistor |
| Standby supply current IS | 2 µA max - minimizes battery drain in always-on vehicle modules |
| TJ operating range | -40 °C to 150 °C - meets under-hood thermal requirements for engine bay placement |
| AEC-Q100 grade | Grade 0 (−40 °C to +150 °C) - qualified for critical automotive power applications |
Pinout & Package
Package: PQFN-12x12 power leadless (16-pin, exposed thermal pad). Thermal resistance Rthj-case = 0.35 °C/W (one channel ON).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Accepts 4.5–28 V DC; clamped to 41–52 V during transients |
| GND | Power ground reference | Common return for load current, logic, and sense circuitry |
| OUT1, OUT2 | High-side power outputs | Switched 12 V outputs driving grounded loads; each rated for 90 A short-circuit |
| IN1, IN2 | CMOS-compatible control inputs | 3.0 V/5.0 V logic compatible with hysteresis (0.25 V); drive internal gate |
| CS1, CS2 | Analog current sense outputs | Deliver ISENSE = IOUT/K0; enable real-time diagnostics and closed-loop control |
| DE | Diagnostic enable | Active-high signal enabling current sense and fault reporting; disables sensing when low |
Key Features
| Feature | Design Value |
|---|---|
| Proportional analog current sense | ±5% full-scale accuracy over -40 °C to 150 °C enables precise load monitoring without external shunt |
| Off-state open-load detection | Validated at VCC = 13 V, Tj = 25 °C - identifies disconnected loads before activation |
| Reverse battery protection | Self-switching MOSFET activation at -13 V - prevents damage during incorrect jump-start |
| Thermal shutdown with auto-restart | Triggers at 150 °C, resets at 135 °C - maintains functionality after transient overloads |
| Load dump immunity | Withstands 41 V transient for <400 ms - compliant with ISO 7637-2 Pulse 5a |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS4H160-Q1 | Single-channel, 1.6 mΩ RON, no analog current sense - uses digital SPI diagnostics | Requires microcontroller with SPI interface; lacks analog ISENSE for analog feedback loops | Choose when system-level diagnostics are handled digitally and lower RON is prioritized over analog sensing |
| VNQ5E025AKTR-E | Dual-channel, 25 mΩ RON, same package and pinout - lower current capability (14 A typ) | Targeted for low-power body electronics; not suitable for high-current solenoids or motors | Choose for cost-sensitive non-critical loads where 4 mΩ RON and 90 A ILIMH are unnecessary |
Compared with TPS4H160-Q1 and VNQ5E025AKTR-E, VND5E004ATR-E uniquely combines dual-channel 4 mΩ switching, analog current sense with ±5% accuracy, and AEC-Q100 Grade 0 qualification - making it optimal for high-reliability, high-current automotive power distribution where analog feedback and thermal resilience are mandatory.

FAQ
What is the maximum transient voltage VND5E004ATR-E can withstand?
The device withstands 41 V transient supply voltage for durations under 400 ms with load resistance >0.5 Ω, per ISO 7637-2 Pulse 5a specifications. Its internal overvoltage clamp activates at 41–52 V, protecting downstream circuitry without external components.
How does the current sense function behave when the DE pin is low?
When DE is pulled low, the analog current sense function is disabled for both channels, and the CS1/CS2 pins enter high-impedance state. This allows sharing of a single external sense resistor across multiple devices in multi-channel systems, reducing component count and layout complexity.
Can VND5E004ATR-E drive inductive loads like solenoids without external flyback protection?
Yes - the device integrates active demagnetization energy management and output voltage clamping (VDEMAG = VCC−32 V typical) to safely dissipate inductive kickback. No external flyback diode is required for standard 12 V solenoid loads per application note AN4723.
What is the thermal performance difference between MultiPowerSO-30 and PQFN-12x12 packages?
The PQFN-12x12 package achieves Rthj-case = 0.35 °C/W (one channel ON), 3× better than MultiPowerSO-30's 1.0 °C/W. This enables higher continuous current in space-constrained layouts and reduces heatsink requirements in under-hood applications.
