Product details

Overview

VN5160S-E from STMicroelectronics is a single-channel automotive high-side driver IC designed for controlling resistive, inductive, and capacitive loads connected to ground. It features 160 mΩ on-state resistance (R_ON), 5.4 A typical current limitation (I_LIMH), 4.5–36 V operating supply range, and integrated open-load detection in both on- and off-states - enabling robust load monitoring in body control modules and lighting systems.

For engineers reviewing the VN5160S-E datasheet, VN5160S-E pinout, VN5160S-E application, or VN5160S-E equivalent, key selection criteria include its SO-8 package thermal performance (R_thj-amb up to 30 °C/W), reverse battery protection capability, CMOS-compatible 3.0 V logic input, and diagnostic status output with STAT_DIS control - all critical for ISO 16750-compliant automotive power distribution designs.

Technical Context

The VN5160S-E integrates VIPower M0-5 technology to combine power MOSFET switching with analog sensing and digital diagnostics in a monolithic high-side configuration. Its active power limitation manages inrush current without external components, while dual-mode open-load detection (on-state current threshold ≤40 mA; off-state voltage threshold ≥2 V) enables fault identification across load states.

Protection architecture includes undervoltage shutdown (V_USD = 4.5 V), thermal shutdown at 150 °C with 135 °C auto-restart, output short-to-V_CC detection, and ESD immunity (±4 kV HBM on INPUT/STATUS/STAT_DIS). The STATUS pin operates as an open-drain diagnostic output, configurable via STAT_DIS to enter high-impedance mode during system sleep.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage range	4.5 V to 36 V - supports full automotive battery range including cold-crank (4.5 V) and load-dump transients (up to 41 V absolute max).
On-state resistance	160 mΩ @ 1 A, 25 °C - ensures <160 mV conduction loss at 1 A, minimizing self-heating in continuous-duty applications.
Current limitation	5.4 A typical (I_LIMH) - provides overload protection without external current-sense resistors or feedback loops.
Standby supply current	2 µA @ V_CC = 13 V - enables ultra-low-power sleep mode in always-on vehicle networks (e.g., door modules).
Logic input compatibility	3.0 V CMOS - interfaces directly with 3.3 V microcontrollers without level-shifting circuitry.
Open-load detection	On-state: detects I_OUT < 10–40 mA; Off-state: detects V_OUT > 2–4 V - enables fail-safe diagnosis of disconnected bulbs, solenoids, or relays.
Thermal shutdown	150 °C trip, 135 °C reset - delivers automatic recovery after transient overloads, avoiding permanent latch-off.

Pinout & Package

Package: SO-8 (Small Outline, 8-pin, surface-mount). Thermal resistance junction-to-ambient up to 30 °C/W with standard PCB copper area per Figure 32.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Battery supply input	Accepts 4.5–36 V DC; includes internal clamp diode to limit transients to 41–52 V (I_S = 20 mA).
OUTPUT	High-side power output	Drives load between OUTPUT and GND; rated for 6 A reverse current and internally limited forward current.
GND	Ground reference	Must be protected externally against reverse battery (e.g., series diode/resistor per Figure 28); not internally isolated.
INPUT	CMOS-compatible control input	3.0 V logic threshold with 0.25 V hysteresis; accepts 0–5 V signals; ±1 mA max input current.
STATUS	Open-drain diagnostic output	Reports faults (open load, overtemp, undervoltage) as low-active signal; requires external pull-up resistor.
STAT_DIS	Status disable control	Active-high CMOS input (2.1 V threshold); drives STATUS into high-Z when asserted - reduces system leakage during sleep.

Key Features

Feature	Design Value
Inrush current management	Active power limitation prevents peak current surges during cold-cranking or capacitor charging - eliminates need for external NTC or soft-start circuits.
Diagnostic flexibility	STATUS pin supports both active-fault reporting and high-impedance disable via STAT_DIS - simplifies integration into CAN/LIN-based diagnostic architectures.
Reverse battery resilience	With external GND-line protection (diode or resistor), survives -14 V reverse polarity per Figure 28 - meets ISO 16750-2 requirement for automotive environments.
EMC-optimized switching	Controlled dV/dt (turn-on/off slopes) and optimized layout reduce radiated emissions - passes ISO 7637-2 Pulse 3a/3b (±150 V) without external suppression.
Load dump tolerance	Internal V_CC clamp limits energy dissipation during ISO 7637-2 Pulse 5b (up to +87 V) - protects downstream logic when used with external TVS or Zener clamping.

Use Scenario: Controlling door locks, window lift motors, or mirror actuators in centralized body controllers.

IC Role / Device Role / Timing Role: Robust power delivery with thermal foldback and diagnostic feedback for safety-critical actuator sequencing.

Use Value: Prevents motor stall damage via current limitation; off-state open-load detection confirms mechanical linkage integrity before activation.

IC Role / Device Role / Timing Role: High-temperature-rated (T_j up to 150 °C) high-side switch with thermal shutdown and auto-recovery.

Use Value: Maintains operation under hood temperatures >105 °C; thermal hysteresis (7 °C) prevents oscillation during sustained overload.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
INFINEON BTS50085-1TAD	Higher R_ON (2.5 mΩ), higher I_LIM (10 A), PG-TO263-7 package	Designed for higher-current engine control loads; lacks integrated off-state open-load detection	Select when >8 A continuous current or TO-263 thermal performance is required; verify STATUS signal compatibility.
NXP MC33883	SOIC-16 package, dual-channel, no integrated V_CC clamp, lower I_LIM (3.5 A)	Targeted at dual-output applications (e.g., mirror heating + defogger); requires external transient protection	Choose for space-constrained dual-load control where independent diagnostics per channel are needed.

Compared with VN5160S-E, BTS50085-1TAD offers higher current capacity but larger footprint and no off-state diagnostics, while MC33883 provides dual-channel integration at the cost of reduced transient robustness and lower current rating - making VN5160S-E optimal for single-channel, ISO-compliant, diagnostic-rich automotive body applications.

FAQ

What is the maximum safe operating temperature for VN5160S-E?

The VN5160S-E has a junction operating temperature range of –40 °C to +150 °C, with thermal shutdown triggered at 150 °C and automatic restart at 135 °C. Its SO-8 package achieves R_thj-amb ≤30 °C/W with adequate PCB copper area (per Figure 32), enabling reliable operation in under-hood environments up to 105 °C ambient.

How does the VN5160S-E detect open load in the off-state?

Off-state open-load detection occurs when V_OUT exceeds 2–4 V (V_OL) while INPUT is low and V_CC is 8–16 V. This condition indicates a floating or disconnected load; the STATUS pin asserts low after a 200–1000 µs delay (t_POL), provided STAT_DIS is low. No external biasing is required beyond the standard pull-up on STATUS.

Can VN5160S-E be used without external reverse battery protection?

No. The GND pin must be protected externally using either a series diode or resistor network (per Figure 28) to withstand reverse battery conditions. The device itself does not integrate reverse-polarity protection on GND; failure to implement this external network risks permanent damage during –14 V exposure.

What is the purpose of the STAT_DIS pin?

STAT_DIS is an active-high CMOS input that places the STATUS pin in high-impedance state when driven high (≥2.1 V). This feature reduces system standby current by disabling STATUS pull-up leakage during vehicle sleep modes, supporting ultra-low-power requirements in always-on domains like alarm systems or telematics gateways.
