Product details
Overview
VND5E050MJ-E from STMicroelectronics is a double-channel high-side driver IC for automotive 12 V grounded loads, featuring integrated analog current sense per channel, 50 mΩ typical on-state resistance, 27 A typical current limitation, and CMOS-compatible 3.0 V logic inputs. It delivers active inrush management, thermal shutdown with auto-restart, and reverse-battery protection-used in body control modules for LED headlamp switching and solenoid actuation.
For engineers reviewing the VND5E050MJ-E datasheet, VND5E050MJ-E pinout, VND5E050MJ-E application, or VND5E050MJ-E equivalent, key selection criteria include channel-isolated current sensing accuracy (±15% K-ratio drift over temperature), PowerSSO-12 package thermal resistance (2.7 °C/W junction-to-case), diagnostic disable functionality via CS_DIS, and compliance with ISO/TS 16949 transient robustness requirements.
Technical Context
This device implements two independent VIPower™ M0-5 high-side switches with dedicated analog current sense outputs (CS1/CS2) and a shared CMOS-compatible CS_DIS enable. Each channel integrates power-limiting overload protection, voltage-clamp overvoltage protection, and thermal shutdown with hysteresis (TTSD = 150–200 °C, THYST = 7 °C).
It operates across 4.5–28 V supply range with undervoltage lockout (VUSD = 4.5 V typ., hysteresis = 0.5 V), supports reverse-battery conditions up to –0.3 V at VCC, and delivers fast switching (td(on) = 20 µs, td(off) = 45 µs) while maintaining <2 µA standby current with all loads connected.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Channels | 2 independent high-side switches with isolated current sense paths |
| RON (typ.) | 50 mΩ per channel at 25 °C - enables low conduction loss for 27 A peak load current |
| ILIMH (typ.) | 27 A at VCC = 13 V - sets hard current limit during short-circuit to ground |
| VCC Range | 4.5 V to 28 V - supports cold-crank (4.5 V) and load-dump (28 V) automotive transients |
| IS (off-state) | 2 µA typical - ensures ultra-low quiescent current for always-on vehicle modules |
| Current Sense Ratio (K1) | 1750 ±15% - maps 1 A load current to ~571 µA sense output, enabling precise external ADC measurement |
| Thermal Shutdown | 150 °C trip with 7 °C hysteresis and auto-restart - prevents latch-up during intermittent overload |
Pinout & Package
Package: PowerSSO-12 (exposed tab connected to VCC), surface-mount, thermally enhanced for automotive under-hood use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Battery supply input | Primary power rail; exposed tab tied to VCC for thermal conduction and EMI reduction |
| GND | Ground reference | Must be externally protected against reverse battery via diode/resistor network per Figure 29 |
| IN1, IN2 | CMOS-compatible control inputs | Hysteresis-enabled (0.25 V), 3.0 V logic compatible; drive internal gate drivers |
| OUT1, OUT2 | High-side power outputs | Switched 12 V loads to ground; each supports 27 A short-circuit current limiting |
| CS1, CS2 | Analog current sense outputs | Deliver proportional current (ISENSE = IOUT/K) for real-time load monitoring and fault detection |
| CS_DIS | Current sense disable control | Active-high CMOS input; disables both CS1/CS2 to share external sense resistor across multiple devices |
Key Features
| Feature | Design Value |
|---|---|
| Inrush current active management | Power-limiting architecture dynamically caps dI/dt during capacitive load turn-on, reducing stress on upstream fuses and wiring |
| Proportional analog current sense | Two independent, temperature-compensated sense channels (K1 = 1750 ±15%) enable simultaneous load diagnostics without multiplexing delay |
| Reverse battery protection | Integrated clamp allows safe operation down to –0.3 V VCC; external GND network (Figure 29) extends protection to full –14 V |
| Overtemperature auto-restart | Thermal shutdown at 150 °C with 7 °C hysteresis and automatic recovery - avoids permanent latch-off during transient overloads |
| EMC-optimized switching | Controlled dV/dt (see Figures 23/25) and layout-aware PowerSSO-12 package reduce radiated emissions in noisy automotive environments |
Applications
| Automotive Body Control Module (BCM) | LED Headlamp Driver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VND5E025MJ-E | Lower RON (25 mΩ typ.), same PowerSSO-12 package, but reduced ILIMH (18 A typ.) | Better for lower-power loads (e.g., small actuators); less suitable for fan motors or high-current LEDs | Select when conduction loss dominates thermal design and peak current ≤18 A |
| TPS27082LDR | Single-channel, 36 V max VCC, no integrated current sense; requires external sense resistor and amplifier | Lacks analog current sense and thermal auto-restart; suited for non-safety-critical industrial loads | Choose only if automotive qualification (AEC-Q100) and dual-channel integration are not required |
Compared with VND5E050MJ-E, VND5E025MJ-E trades higher current capability for lower on-resistance, while TPS27082LDR sacrifices automotive-grade diagnostics and dual-channel integration for broader supply voltage range and simpler control interface.

FAQ
What is the maximum allowable reverse battery voltage at the VCC pin?
The absolute maximum rating for reverse DC supply voltage at VCC is –0.3 V. To withstand full automotive reverse-battery conditions (–14 V), an external protection network-such as a series diode or resistor in the GND line per Figure 29-is mandatory. The device itself does not tolerate sustained negative VCC beyond –0.3 V.
Can CS1 and CS2 be used simultaneously with a single external sense resistor?
No-CS1 and CS2 are independent current-output pins and cannot share one resistor without signal interference. However, pulling CS_DIS high disables both sense outputs, allowing external circuitry to reuse the same sense resistor across multiple VND5E050MJ-E devices in time-multiplexed configurations.
How does the power limitation function respond during inductive load turn-off?
During turn-off of inductive loads, the device activates its VDEMAG clamp (VCC – 41 V typ.) to limit flyback voltage, while simultaneously engaging power limitation to cap peak current. This dual action prevents destructive voltage spikes and controls demagnetization energy, with maximum rated switching energy of 104 mJ per pulse (L = 3 mH, Vbat = 13.5 V).
Is the PowerSSO-12 package RoHS-compliant and halogen-free?
Yes-the VND5E050MJ-E uses ST's ECOPACK®-compliant PowerSSO-12 package, meeting EU Directive 2002/95/EC (RoHS) and containing no brominated flame retardants or chlorine-based materials. Full material declarations and test reports are available under ST's ECOPACK® program documentation.
