Product details

Overview

VND5E050MK-E from STMicroelectronics is a double-channel high-side driver IC in PowerSSO-24 package, designed for 12 V automotive grounded loads. It delivers 50 mΩ on-state resistance per channel, 27 A typical current limitation, and proportional analog current sense (K₀ = 2250) with ±15% ratio drift over temperature. Used in LED headlamp control and body electronics for precise load switching with thermal shutdown and reverse-battery protection.

For engineers reviewing the VND5E050MK-E datasheet, VND5E050MK-E pinout, VND5E050MK-E application, or VND5E050MK-E equivalent, this page provides verified technical context, diagnostic behavior under overload, current-sense disable functionality, and automotive-grade protection timing - all confirmed from ST's official Doc ID 15532 Rev 2.

Technical Context

The device integrates two independent VIPower™ M0-5 high-side switches with dedicated analog current sense pins (CS1/CS2) and a shared CMOS-compatible CS_DIS input. Each channel implements active power limitation during inrush and short-circuit events, with thermal shutdown at 150 °C and auto-restart after cooling to ≥135 °C.

Protections include undervoltage lockout (4.5 V), overvoltage clamp (46 V), reverse-battery tolerance via external GND network, and ESD robustness (4 kV HBM on IN/CS pins). Diagnostic feedback is delivered through proportional ISENSE current (not voltage), enabling microcontroller-based load monitoring without external shunts.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V DC - withstands automotive load-dump transients up to ISO 7637-2 Pulse 5a.
Operating voltage range	4.5 V to 28 V - supports cold-crank (4.5 V) and boosted battery (28 V) conditions.
R_ON (per channel)	50 mΩ @ 25 °C - limits conduction loss to ≤200 mW at 2 A, enabling compact thermal design.
Current limit (typ)	27 A - sustains short-circuit events while limiting peak junction temperature rise.
Standby current	2 µA - enables always-on modules (e.g., door control) without battery drain.
Current sense ratio	K₀ = 2250 (I_OUT/I_SENSE) - allows 1 mA sense current to represent 2.25 A load current.
Thermal shutdown	150 °C with 7 °C hysteresis - prevents permanent damage during sustained overload.

Pinout & Package

Package: PowerSSO-24 (exposed thermal pad tied to VCC, 24-pin surface-mount, RoHS-compliant).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Primary power rail; connects to exposed thermal tab for enhanced heat dissipation.
GND	Ground reference	Must be protected against reverse battery via external diode/resistor network per Figure 29.
IN1, IN2	CMOS-compatible control inputs	Hysteresis (0.25 V) prevents noise-induced switching; compatible with 3 V/5 V MCUs.
OUT1, OUT2	High-side power outputs	Drive grounded resistive/inductive/capacitive loads; each supports 27 A short-circuit current.
CS1, CS2	Analog current sense outputs	Deliver proportional current (I_SENSE = I_OUT/K₀); require external sense resistor to ground.
CS_DIS	Active-high current sense disable	Pulling high disables both CS1/CS2, enabling shared sense resistor across multiple devices.

Key Features

Feature	Design Value
Inrush current management	Active power limitation prevents voltage sag during capacitive load turn-on (e.g., LED arrays).
Proportional current sensing	±15% full-temperature-range accuracy enables closed-loop load monitoring without calibration.
Reverse battery protection	Withstands -13.5 V applied to GND when used with external DGND/RGND network (Figure 29).
Overvoltage clamp	Clamps to 46 V during load dump, eliminating need for external TVS diodes in many designs.
Thermal auto-restart	Resumes operation after cooling below 135 °C, avoiding system latch-up during intermittent faults.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
VND5E025MK-E	Lower R_ON (25 mΩ), 35 A current limit, same PowerSSO-24 package and pinout.	Better suited for higher-current loads (e.g., heated seats) but consumes more PCB area due to larger die.	Select when lower conduction loss is critical and thermal margin permits higher power density.
TPS4H160-Q1	Single-channel, 160 mΩ R_ON, integrated SPI interface, no analog current sense output.	Requires MCU with SPI support; lacks direct analog feedback for simple ADC-based monitoring.	Choose for systems needing programmable diagnostics and multi-device daisy-chaining over analog simplicity.

Compared with VND5E050MK-E, the VND5E025MK-E offers superior current handling at the cost of higher thermal stress, while the TPS4H160-Q1 trades analog diagnostic immediacy for digital configurability and channel scalability - making VND5E050MK-E optimal for cost-sensitive, dual-channel, analog-diagnostic automotive nodes.

FAQ

What is the maximum continuous output current per channel?

The VND5E050MK-E does not specify a continuous current rating; its 27 A value is the typical short-circuit current limit under active power limitation. Continuous current depends on PCB copper area, ambient temperature, and thermal design - with 2 A achievable at 25 °C ambient using 10 cm² of 2 oz copper per channel in PowerSSO-24, per Figure 37.

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 outputs, allowing external multiplexing of a single sense resistor across multiple VND5E050MK-E devices in time-division mode, as described in Section 3.4.

Is reverse-battery protection internal or external?

Reverse-battery protection is external: the device requires an external diode (DGND) or resistor (RGND) in the ground path per Figure 29. The IC itself tolerates reverse GND voltage only up to -0.3 V; beyond that, external network implementation is mandatory for automotive compliance.

Does the thermal shutdown feature latch or auto-restart?

The thermal shutdown is auto-restarting: when junction temperature exceeds 150 °C, the device shuts down and resumes normal operation once temperature falls below 135 °C (15 °C hysteresis). This behavior is confirmed in Table 8 and Figure 13, enabling fault recovery without MCU intervention.
