VND5160AJTRE 概要
What is a high-side driver? A high-side driver is a type of power switch that sits between the positive supply rail and the load, allowing the MCU ground-referenced logic to switch the positive rail to a grounded load such as a bulb, solenoid, or DC motor. In the broader semiconductor taxonomy, the high-side driver sits within smart power ICs, which sit within power management ICs. Compared to a discrete MOSFET plus gate driver, an integrated smart high-side switch saves board area, adds load-current diagnostics, and provides on-chip protection against short circuits, open loads, and thermal overload.
Key features of the VND5160AJTRE include 41 V load-dump-tolerant V<sub>CC</sub> rating, 3.8 A continuous current per channel (limited thermally), 60 mΩ R<sub>DS(on)</sub> at 25 °C, very low quiescent current for standby operation, fast demagnetization of inductive loads, and a CS_DIS pin for multiplexing current sense. The analog current-sense output allows the host MCU to detect partial loads, shorts to ground, and open-circuit conditions without additional shunt resistors.
The VIPower M0-3 process combines a vertical N-channel DMOS output stage with bipolar and CMOS analog/mixed-signal circuitry on the same die. This monolithic integration reduces parasitic inductance, simplifies PCB layout, and provides intelligent protection features including thermal shutdown, current limitation, and load-dump transient clamping per ISO 7637.
Typical applications include automotive body electronics such as LED lighting drivers, HVAC relays, door-lock actuators, seat heaters, and small DC motor control. The wide V<sub>CC</sub> tolerance and analog current sense make it well suited for replacing electromechanical relays with solid-state switching in body control modules.
When designing with this part, place the VND5160CC charge-pump capacitor and bootstrap components as close to the IC as possible, ensure adequate copper heat sinking for thermal dissipation, and use the VND5160's analog current sense with an external sense resistor to monitor load health. The exposed pad must be soldered to a sufficiently large copper pour for thermal dissipation; undersized PCB copper will trigger thermal shutdown at lower than expected currents.
This page synthesizes distributor pricing, drop-in PowerSSO-12 alternatives, and practical design notes that go beyond what the manufacturer datasheet alone provides, including cross-references to second-source parts vetted for the same PCB footprint.

安全動作領域
主な用途
VND5160AJTRE の用途: 6 件s: Automotive LED Lighting Driver, Body Electronics Relay Replacement, HVAC Flap Motor Control, Door Lock Actuator Drive, Seat Heater Control Module, Industrial 24V PLC Output Module.
Automotive LED Lighting Driver
Why VND5160AJTRE fits LED lighting: The 3.8 A continuous per-channel current and 60 mOhm R<sub>DS(on)</sub> deliver very low dropout on automotive 12V rails while keeping thermal dissipation modest for LED strings. How it is used: Each channel sources the LED module anode with the cathode returned to ground; the CS_DIS-driven analog current sense feeds an MCU ADC for closed-loop brightness feedback and open-LED detection. Performance consideration: Unlike a discrete MOSFET plus gate driver, the integrated VIPower switch provides thermal shutdown at TAMB around 150 C; the exposed pad must be soldered to sufficient copper to achieve the rated thermal performance.
おすすめ
Body Electronics Relay Replacement
Why VND5160AJTRE fits relay replacement: The 41V VCC tolerance covers 12V automotive transients including load-dump, replacing electromechanical relays with solid-state switching improves reliability and reduces audible click noise. How it is used: Driven directly from a 5V-tolerant logic output of the BCM MCU; the input pin tolerates PWM for dimming or soft-start, while the integrated analog current sense replaces shunt-resistor current monitoring. Performance consideration: Compared to a mechanical relay, the VND5160AJTRE adds milliamp-range diagnostic current sense but introduces ~60 mOhm of voltage drop, acceptable for sub-3 A loads.
おすすめ
HVAC Flap Motor Control
Why VND5160AJTRE fits HVAC motors: Dual independent channels in a compact PowerSSO-12 footprint drive bi-directional small DC brush motors via H-bridge pairing without a separate driver IC. How it is used: One VND5160AJTRE drives the high side of each motor leg; direction is selected by alternating which two channels are enabled. Performance consideration: The 28V operating ceiling comfortably exceeds 12V automotive nominal with headroom for jump-start transients up to about 18V.
おすすめ
Door Lock Actuator Drive
Why VND5160AJTRE fits door lock actuators: Each of the two channels is rated 3.8 A continuous, well above the locked-rotor stall current of typical 12V door-lock actuators. How it is used: Channel A drives the lock direction, Channel B drives the unlock direction in a half-bridge configuration; the analog current sense detects end-of-travel stall so the MCU can cut power to prevent motor burnout. Performance consideration: The integrated active VCC clamp handles reverse-EMF from the actuator without an external flyback diode, simplifying PCB layout.
おすすめ
Seat Heater Control Module
Why VND5160AJTRE fits seat heaters: Two independent channels allow driver-side and passenger-side heating elements to be driven from a single PowerSSO-12 IC, with PWM modulation from the BCM for closed-loop temperature control. How it is used: The two channels drive separate heating pads; the analog current sense provides load-current feedback proportional to element resistance, which the MCU uses to detect open-circuit failures. Performance consideration: The 41V load-dump tolerance ensures survival of jump-start and load-dump events common in automotive power buses.
おすすめ
Industrial 24V PLC Output Module
Why VND5160AJTRE fits PLC outputs: Industrial 24V PLC output modules require 24V-tolerant switches with galvanically isolated diagnostics; the VND5160AJTRE's 28V operating ceiling covers 24V nominal with margin. How it is used: Each channel sources a 24V field device such as a solenoid or indicator lamp; the analog current-sense output is buffered through an optocoupler back to the central PLC controller. Performance consideration: AEC-Q100 automotive grade qualification implies robust ESD and thermal performance suitable for industrial environments, though the part is primarily automotive-targeted.

設計ノート
The PowerSSO-12 exposed pad must be soldered to a thermal copper pour of at least 1 square inch of 1 oz copper to achieve the rated 3.8 A continuous current per channel; undersized copper will trigger thermal shutdown at lower than expected currents. For sustained dual-channel operation near full load, expand the pour to 2-3 square inches or add bottom-side thermal vias to dissipate approximately 1 W per channel at full load on 12V rails.
Verify the input pin voltage levels match your MCU logic: the VND5160AJTRE logic inputs are CMOS-compatible and tolerate 5V directly without level shifters, but check the VCC min of 4.5V before enabling the channels. Do not float the CS_DIS pin - leave it open or drive it low for normal analog current-sense operation; an undefined level can leave the sense pin floating and corrupt diagnostics.
Place the sense resistor and decoupling capacitors directly adjacent to the IC pins - keep the analog CS trace short and routed away from the OUT1/OUT2 power traces to minimize noise coupling. The exposed pad requires multiple thermal vias (8-12 vias in a 1.2 mm pitch array is typical) connecting top copper to internal ground planes for efficient heat extraction from the PowerSSO-12 package.
