Product details

Overview

VND5160AJTR-E from STMicroelectronics is a dual-channel automotive high-side driver with integrated analog current sense, designed for driving resistive, inductive, or capacitive loads connected to ground. It features 160 mΩ max on-state resistance per channel, 5 A typical current limitation, 4.5–36 V operating supply range, and CMOS-compatible 3.0 V logic inputs. Used in body control modules for LED lighting and solenoid actuation.

For engineers reviewing the VND5160AJTR-E datasheet, VND5160AJTR-E pinout, VND5160AJTR-E application, or VND5160AJTR-E equivalent, key selection criteria include proportional current sense accuracy (±13% drift over temperature), reverse battery protection capability, thermal shutdown with auto-restart, and ISO 7637-2 Pulse III/IV transient compliance for 12 V automotive systems.

Technical Context

The device implements two independent VIPower M0-3 high-side switches with active power limitation during inrush, enabling robust drive of incandescent lamps and relay coils without external current limiting. Each channel integrates a precision current mirror delivering I_SENSE = I_LOAD/K (K = 260–750), with CS_DIS enabling high-impedance disable mode.

Protection architecture includes undervoltage lockout (4.5 V trip), V_CC clamp (41 V), self-limiting thermal response, and loss-of-ground/V_CC detection. Diagnostic outputs provide real-time thermal shutdown indication and open-load detection via current sense leakage monitoring.

Key Specifications

Parameter	Value and Actual Design Meaning
Max supply voltage	41 V - withstands load dump transients per ISO 7637-2 Pulse IV (-100 V spike).
Operating voltage range	4.5 V to 36 V - supports cold-crank (4.5 V) and 24 V commercial vehicle systems.
On-state resistance (per ch.)	160 mΩ (typ. at 25°C) - limits conduction loss to ≤1.28 W at 4 A, enabling compact thermal design.
Current limitation (typ.)	5 A - sustains short-circuit conditions without external fusing while limiting junction temperature rise.
Standby supply current	2 µA - enables always-on functions in low-power body electronics without battery drain.
Current sense ratio (K)	260–750 (I_OUT/I_SENSE) - supports accurate 1–1.5 A sensing with ±13% drift across -40°C to 150°C.
Turn-off delay time	15 µs (typ.) - ensures fast deactivation for PWM dimming of LEDs and precise timing in safety-critical actuators.

Pinout & Package

Supplied in PowerSSO-12™ package: thermally enhanced exposed pad (V_CC-connected tab), 12-pin surface-mount with backward-compatible pinout (pins 7 and 12 are V_CC N.C. per PCN-APG-BOD/07/2886).

Pin/Terminal	Circuit Role	Design Meaning
V_CC	Battery supply input	Primary power rail; clamped to 41 V internally; pins 7 & 12 are no-connect in new layouts but tied to V_CC for legacy compatibility.
GND	Ground reference	Must be protected against reverse battery via external diode/resistor network per Figure 26.
INPUT1 / INPUT2	CMOS logic control inputs	3.0 V compatible; 0.9 V/2.1 V thresholds with 0.25 V hysteresis for noise immunity in harsh automotive environments.
OUTPUT1 / OUTPUT2	High-side switched outputs	Drive loads between OUTPUTx and GND; support inductive demagnetization energy up to 34 mJ (L=12 mH, V_BAT=13.5 V).
CURRENT SENSE1 / CURRENT SENSE2	Analog current feedback outputs	Deliver I_SENSE = I_LOAD/K; require external 3.9 kΩ pull-up for overtemperature flag (V_SENSEH = 9 V).
CS_DIS	Current sense enable/disable	Active-high CMOS input; drives CURRENT SENSE pins to high-Z when high, eliminating quiescent sense current.

Key Features

Feature	Design Value
Inrush current management	Active power limitation prevents voltage sag during lamp cold-start, eliminating need for external soft-start circuitry.
Proportional current sense	Factory-trimmed K-ratio (260–750) with <±13% drift over full temperature range enables closed-loop load monitoring without calibration.
Reverse battery protection	Integrated GND protection network compatibility (resistor/diode solutions in Fig 21–22) meets automotive reverse-polarity requirements.
Thermal shutdown with auto-restart	Triggers at 150°C (T_TSD), resets at 135°C (T_R); allows recovery after fault removal without MCU intervention.
ISO 7637-2 transient immunity	Withstands 5000 pulses of -75 V (Pulse III) and -100 V (Pulse IV) without latch-up or parameter shift.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS27082LDR	Single-channel, 85 mΩ R_ON, no integrated current sense, 36 V max, 2.5 V logic compatible.	Lacks analog current monitoring; requires external sense resistor and ADC for diagnostics.	Preferred where cost-sensitive single-load control without diagnostics suffices.
VND7140AJTR-E	Dual-channel, 200 mΩ R_ON, 4 A ILIM, identical PowerSSO-12 package, same current sense architecture (K=250–700).	Lower current rating and higher R_ON; optimized for lower-power loads like sensors and small relays.	Select when 4 A limit and marginally relaxed thermal performance meet system requirements.

Compared with TPS27082LDR, VND5160AJTR-E provides integrated diagnostics and dual-channel consolidation; versus VND7140AJTR-E, it delivers 25% higher current capability and 20% lower conduction loss, critical for high-power lighting and actuation.

FAQ

What is the maximum continuous output current per channel?

The VND5160AJTR-E provides 5 A typical current limitation (I_LIMH) under DC short-circuit conditions at V_CC = 13 V. Continuous safe operating current depends on PCB thermal design: with 100 cm² copper area, it supports ≥3.5 A per channel at 85°C ambient per Figure 29. Derating is required above 100°C junction temperature.

How does the current sense function operate with CS_DIS?

When CS_DIS is driven low or left floating, each CURRENT SENSE pin delivers I_SENSE = I_LOAD/K (K = 260–750). When CS_DIS is driven high (≥2.1 V), the CURRENT SENSE pin enters high-impedance state (<1 µA leakage), disabling analog feedback and reducing system power consumption during standby.

Is reverse battery protection built-in or external?

Reverse battery protection requires external implementation per Figure 26: either a series resistor (R_GND) or diode (D_GND) in the GND path. The IC itself tolerates -0.3 V on V_CC and -0.7 V on CS_DIS but does not protect GND from reverse polarity without external components.

Can VND5160AJTR-E drive inductive loads without external flyback diodes?

No external flyback diode is required: the device integrates an internal clamp that limits V_OUT to V_CC − 41 V during demagnetization (Table 9, V_DEMAG). This protects the output stage from inductive kickback up to 34 mJ (L = 12 mH, V_BAT = 13.5 V), verified per ISO 7637-2 Pulse IV testing.
