VN5025AJTR-E - 25V 28A Single High-Side Driver | STMicroelectronics
MPN: VN5025AJTR-E ✓ NakahandaVN5025AJTR-E Ulas
Key features include an integrated analog current-mirror output that delivers a sense current proportional to the load current for diagnostic feedback, an active VCC clamp that absorbs low-energy transient spikes per the ISO7637 specification, and very low quiescent current draw for battery-friendly standby behaviour. The driver uses STMicroelectronics VIPower vertical-DMOS technology for low on-state resistance of 35 mOhm typical, which keeps conduction losses low at high continuous current.
The VN5025AJ-E employs a monolithic VIPower M0-3 architecture that integrates a charge pump, gate driver, output power MOSFET, and protection circuitry on one die. The analog current sense output removes the need for an external shunt resistor in many applications, while built-in protections cover over-current, over-temperature, under-voltage, and load-dump conditions, which is critical for meeting automotive EMC requirements.
Typical applications include driving automotive resistive loads such as LED arrays and incandescent lamps, switching inductive loads such as solenoids, relays and small DC motors, and replacing electromechanical relays in body electronics modules, lighting controllers and dashboard switch inputs.
When designing with this part, evaluate the thermal resistance of the PowerSSO-12 PCB footprint - a copper pad of at least 6 square centimetres is recommended to handle the full 28 A continuous load. The analog sense pin requires a small filter capacitor and a sense resistor sized according to the maximum expected load current.

Tipikal na mga Gamit
VN5025AJTR-E ay nararapat para sa 6 aplikasyons: Automotive LED Lighting Driver, Body Control Module Load Switch, Industrial 24V Solenoid and Relay Driver, Automotive HVAC Blower Motor Drive, Dashboard Switch and Indicator Driver, Battery Disconnect and Anti-Theft Switch.
Automotive LED Lighting Driver
The VN5025AJTR-E is well suited for direct drive of automotive 12V LED strings (interior lighting, daytime running lights, position lamps) thanks to its 4.5V to 41V wide Vcc range and 28A continuous load capability. Its integrated analog current sense eliminates the need for an external shunt resistor in the return path, simplifying the harness and reducing parasitic losses, while the 35 mOhm RDS(on) keeps thermal dissipation manageable when switching multiple LED channels from one BCM. The ISO7637 transient clamp on VCC protects the lamp driver from load-dump and jump-start surges encountered on real vehicle 12V buses.

Body Control Module Load Switch
In a body control module the VN5025AJTR-E serves as a high-side driver for actuators such as door-lock solenoids, mirror heaters, and seat-adjustment motors. Its monolithic VIPower construction, including charge pump, gate driver, MOSFET, and analog sense, replaces an electromechanical relay with a solid-state switch that has unlimited mechanical life. The diagnostic current sense is fed back to the STM32 host for open-circuit, short-to-ground, and over-current detection per automotive UDS requirements.

Industrial 24V Solenoid and Relay Driver
The VN5025AJTR-E is commonly used to drive 24V industrial solenoids and signal relays in PLC output modules where load-ground-referenced switching is required. The 41V Vcc ceiling handles 24V nominal rails with sufficient transient margin without an external TVS, while the 28A continuous rating allows multiple parallel coils to be sourced from one driver stage. Built-in thermal shutdown protects against stalled-load conditions common in pneumatic systems.

Automotive HVAC Blower Motor Drive
For brushed DC blower motors in automotive HVAC systems the VN5025AJTR-E offers a compact, single-package replacement for relay-based power stages. PWM control via the logic input allows software-variable speed, while the analog sense output provides a tachometer-free indication of stall or over-current without adding a sense resistor. Thermal performance is dominated by the PowerSSO-12 footprint, which on typical 2 oz FR4 copper dissipates up to 3W continuously without additional heatsinking.

Dashboard Switch and Indicator Driver
Driving indicator LEDs, warning lamps, and switch backlights from a central instrument-cluster module is a typical VN5025AJTR-E application. The device's 28A rating allows one channel to multiplex several low-current lamps sequentially without exceeding thermal limits, while the analog sense confirms each lamp element is actually drawing current for open-circuit detection. Combined with ST's AEC-Q100 ecosystem this enables designers to maintain a single qualification path for the cluster electronics.
Inirekomenda
Battery Disconnect and Anti-Theft Switch
The VN5025AJTR-E is frequently used as a solid-state battery-disconnect switch in anti-theft and load-shedding circuits where a low quiescent current is mandatory. The TTL-level input allows the host MCU to wake the system by toggling the gate, while the analog sense output provides a hardware-level proof that load current is actually flowing, enabling safe de-energisation. The 41V Vcc headroom lets the same hardware survive jump-start events from neighbour vehicles.

Talaan ng Disenyo
Power dissipation in the VN5025AJTR-E is dominated by I^2*RDS(on). Estimated: at 28 A continuous load and a typical 35 mOhm on-state resistance, conduction loss reaches roughly 27.5 W; this must be sunk through a copper pour of at least 6 square centimetres on the PowerSSO-12 PCB footprint, or the junction will exceed the +150 C shutdown threshold.
The exposed pad on PowerSSO-12 is electrically isolated from ground and must be soldered to a copper area that ties back to GND or VCC, but is not part of the current-carrying path. Also confirm that the analog sense pin sees a real load before relying on its diagnostic value - the sense current is referenced to ground return, not to the load itself.
Estimated: keep the high-current OUT trace at least 2 mm wide for every 5 A and provide a wide return path through the exposed pad copper. Place the sense resistor close to the SENSE pin with a small filter capacitor to ground, and avoid routing the logic INPUT near the OUT trace to minimise dv/dt injection into the control signal.
