Product details

Overview

VN5E160MSTR-E from STMicroelectronics is a single-channel automotive high-side driver in SO-8 package, designed to switch 12 V grounded resistive/inductive/capacitive loads with integrated analog current sensing, thermal shutdown with autorestart, and 160 mΩ R_ON at 25 °C. It delivers precise load current monitoring (K₀ = 490 typ.), 10 A current limitation, and 3.0 V CMOS-compatible input control for microcontroller interfacing in body electronics modules.

For engineers reviewing the VN5E160MSTR-E datasheet, VN5E160MSTR-E pinout, VN5E160MSTR-E application, or VN5E160MSTR-E equivalent, this page provides verified technical context, diagnostic behavior under overload, current sense timing delays (Δt_DSENSE2H = 110 µs), and SO-8 thermal resistance (R_thj-amb per Figure 33) to support functional safety-compliant design validation.

Technical Context

This device implements VIPower™ M0-5 technology to integrate power MOSFET, protection logic, and proportional current sense in one die. Its active power limitation manages inrush and short-circuit events by dynamically clamping output voltage (V_ON ≤ 25 mV at 30 mA) while maintaining thermal stability via self-limiting fast transients and overtemperature shutdown at 150–200 °C with 7 °C hysteresis.

The analog current sense channel delivers temperature-compensated I_OUT/I_SENSE ratios across wide load range (K₃ = 420–490 at 1.5 A), with CS_DIS pin enabling shared external sense resistor usage. Diagnostic outputs include power limitation indication and thermal shutdown flag, both requiring coordinated software response per ST's reliability guidance.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - supports ISO 7637-2 load dump pulses without external clamp
R_ON (typ, 25 °C)	160 mΩ - enables <1.6 W conduction loss at 10 A, reducing heatsink requirements
Current limit (ILIMH)	10 A (typ @ 13 V) - sets safe maximum fault current during short-to-ground
Standby supply current	2 µA - ensures <10 µW quiescent power in vehicle sleep mode
Current sense ratio (K₀)	490 (typ @ 25 mA) - yields ~51 µA sense current per 25 mA load, compatible with 12-bit ADC inputs
Thermal shutdown threshold	150 °C - triggers autorestart after junction cools to 135 °C, preventing latch-up
Input hysteresis	0.25 V - rejects noise on IN/CS_DIS pins in harsh automotive EMI environments

Pinout & Package

Package: SO-8 (ECOPACK® compliant, 150 °C max operating junction temperature, R_thj-pins = 30 °C/W).

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Accepts 4.5–28 V DC; clamped to 46 V during load dump; reverse-battery protected externally
OUT	High-side switched output	Drives grounded loads; features active V_ON limitation (≤25 mV) and demagnetization clamp (V_DEMAG = V_CC − 46 V)
GND	Power ground reference	Must be reverse-battery protected via external diode/resistor network per Section 3.1
IN	CMOS-compatible control input	Hysteresis (0.25 V) enables robust 3.0/5.0 V MCU interface; VIH = 2.1 V min, VIL = 0.9 V max
CS	Analog current sense output	Delivers I_SENSE = I_OUT/K₀; max V_SENSE = 5 V; leakage ≤2 µA at full temp range
CS_DIS	Active-high sense disable	Pulling high disables CS output; VIH = 2.1 V, clamp ±0.7 V to 7 V; hysteresis 0.25 V

Key Features

Feature	Design Value
Inrush current management	Active power limitation prevents peak current surge during cold lamp startup (e.g., halogen headlights)
Proportional current sense	±11% K-ratio drift over −40 to +150 °C enables accurate fault detection without calibration
Overvoltage clamp	46 V clamp at VCC limits energy dissipation during ISO 7637-2 pulse 5a, reducing external TVS cost
Loss-of-ground protection	Internal circuitry detects open GND and forces shutdown, preventing uncontrolled output state
Reverse battery immunity	With external GND network (diode/resistor), survives −14 V applied to VCC for >100 ms per AEC-Q100

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	Higher R_ON (200 mΩ), no analog current sense (digital fault flags only), 40 V max VCC	Lacks proportional current telemetry; suited for binary fault reporting only	Select when diagnostic depth is secondary to cost and footprint (HTSSOP-16 vs SO-8)
BDL100FJ	Lower current limit (6 A), no thermal autorestart (latch-off), 36 V max VCC	Requires external watchdog reset after overtemperature event	Select for non-safety-critical 12 V loads where simplified protection suffices

Compared with TPS4H160-Q1 and BDL100FJ, VN5E160MSTR-E uniquely combines analog current sensing with thermal autorestart and 160 mΩ R_ON, making it optimal for ASIL-B body control nodes requiring continuous load monitoring and fail-operational behavior.

FAQ

What is the maximum continuous output current rating for VN5E160MSTR-E?

The device is rated for 10 A typical DC short-circuit current (I_LIMH) at 13 V V_CC, but continuous current capability depends on PCB thermal design. With 100 cm² copper area, R_thj-amb ≈ 35 °C/W allows ~4.3 A continuous at 125 °C ambient per Figure 33 and thermal derating curves in Section 4.1.

How does the current sense disable (CS_DIS) function interact with shared sense resistor topologies?

When CS_DIS is pulled high, the internal current sense amplifier disconnects from the CS pin, allowing multiple VN5E160MSTR-E devices to share one external sense resistor. The CS pin becomes high-impedance (leakage ≤2 µA), enabling multiplexed ADC sampling without cross-talk or loading errors.

Can VN5E160MSTR-E drive inductive loads without an external freewheeling diode?

No. While the device includes V_DEMAG clamp (V_CC − 46 V) to limit turn-off voltage spikes, this is not a substitute for a freewheeling diode across highly inductive loads like fuel injectors or solenoids. External diodes remain mandatory per Section 3.5 to prevent exceeding absolute maximum ratings.

What is the recommended layout practice for minimizing electromagnetic susceptibility?

Place the GND pin directly beneath the power path (VCC → OUT), use minimum trace lengths for IN and CS_DIS, route CS away from noisy switching nodes, and implement a solid ground plane with ≥2 oz copper. ST recommends 10 kΩ pull-down on unused CS_DIS and avoid floating IN/CS pins per Table 2.
