VND7E050AJTR 개요
A high-side driver (HSD) is a power-management switch that sits between the battery rail and the load, controlling current flow by pulling the load up to Vbat. Compared with low-side switches, high-side drivers permit the chassis-grounded load convention used in automobiles, simplify fault detection on a short-to-ground, and allow the load to be turned off safely while the rest of the harness remains live. Within the broader taxonomy, the VND7E050AJTR belongs to the smart-power switch family that subsumes simple MOSFETs, then integrates diagnostics, protection, and a current-sense analog feedback channel to deliver load-current and chip-temperature telemetry to the body-control ECU.
Key electrical characteristics include dual 50 A continuous outputs, very low standby current (VND7E050 family typically 5 uA standby), analog current-sense (CS) output with multiplexer for load current / VCC / temperature diagnostics, and a dedicated FaultRST pin to unlatch the output after a fault event. The chip features 3 V and 5 V CMOS-compatible inputs, very low quiescent current draw, and STMicroelectronics' VIPower vertical intelligent power process.
Typical use cases include automotive body-domain loads such as LED lighting modules, seat heaters, window lifters, door locks, and small DC motors. The multiplexed current-sense output enables predictive maintenance by detecting bulb-failure or motor-stall events without intrusive shunt resistors.
When designing with the VND7E050AJTR, ensure the heatsink area can dissipate worst-case I²R losses (each channel), respect the reverse-battery and load-dump transient ratings of the VIPower M0-7 process, and assign a unique latch-off behavior for the FaultRST pin. Properly routed PowerSSO-16 copper pours are mandatory to maintain junction temperature below 150 °C.

일반적인 애플리케이션
VND7E050AJTR 적합 용도: 6 애플리케이션s: Automotive LED Headlight Modules, Body Control Modules (BCM) and Door Modules, Seat Heater and Steering Wheel Heater Drivers, Solenoid and Relay Drivers (Starter, Glow Plug, EGR), Industrial 24 V PLC Output Modules, Power Distribution Boxes and Junction Boxes.
Automotive LED Headlight Modules
The VND7E050AJTR's dual 50 A per-channel rating directly supports high-brightness LED headlamp strings drawing 5 A to 15 A per string at 12 V. The analog multiplexed current-sense (CS) output lets the body-control ECU monitor every LED's current in real time, triggering bulb-failure warnings long before the LED goes dark - critical for adaptive-driving-beam (ADB) systems and DRL compliance diagnostics. The configurable-latch overtemperature shutdown of the VIPower M0-7 process protects the headlamp housing from thermal runaway at high ambient under-hood temperatures, while FaultRST allows the ECU to distinguish between an intermittent connection and a persistent short. Compared with a discrete MOSFET solution, the integrated protections eliminate the need for PTC resettable fuses and external TVS diodes in the lamp harness.

Body Control Modules (BCM) and Door Modules
The dual high-side channel topology of the VND7E050AJTR mirrors the load pairs commonly clustered inside a BCM: door-lock motor and mirror-fold motor, or window-lift motor on each side. With 50 A continuous headroom on each output, the IC can drive high-inrush loads like window-lift motors without a parallel MOSFET pre-driver stage. The analog CS pin feeds back to a BCM analog input so the MCU can debounce end-of-travel stops, detect motor stall, and report stuck-switch diagnostics to the CAN bus. Compared with discrete high-side switches, the VND7E050AJTR integrates the 3 V / 5 V CMOS logic interface, eliminating the need for level shifters in 3.3 V BCM designs, and the configurable-latch overtemperature behavior reduces the BCM's reliance on a watchdog MCU.

Seat Heater and Steering Wheel Heater Drivers
Resistive seat heaters are high-current DC loads that benefit from the VND7E050AJTR's analog current sense to verify PWM duty and detect heater-element failure. A typical seat heater draws 8 A to 15 A at 12 V - well within the 50 A per-channel headroom even with cold-start inrush - and the multiplexed CS pin enables the HVAC ECU to log element-resistance drift over the vehicle lifetime. The active-overload power management of VIPower M0-7 limits peak power dissipation during a folded-seat fault condition, and configurable-latch overtemperature shutdown prevents accidental passenger burns. Compared with a low-side MOSFET driver, the high-side topology permits the heater return to be chassis-grounded for cleaner EMC.

Solenoid and Relay Drivers (Starter, Glow Plug, EGR)
The VND7E050AJTR can replace electromechanical relays for low- to medium-power solenoids such as EVAP purge, EGR vacuum, glow-plug relay, and auxiliary starter interlocks. The 50 A continuous capability handles the inrush of a glow-plug relay (typically 30 A per bank) with margin for cold-start spikes, while the active-low FaultRST pin allows the engine ECU to verify continuity at key-on. The integrated load-dump and reverse-battery protection of the VIPower M0-7 process survives the harsh transients of a cranking engine harness, removing the need for an external TVS clamp. Compared with a mechanical relay, the solid-state design eliminates audible click, bounce, and arcing - ideal for premium NVH targets.

Industrial 24 V PLC Output Modules
Outside the automotive cabin, the VND7E050AJTR's 4 V to 28 V operating range makes it a drop-in solid-state output for 24 V industrial PLC sink/source modules. Each high-side output can switch 50 A continuous - well beyond the 0.5 A to 2 A needed per PLC output point - and two channels per IC keep the module channel density high. The multiplexed current-sense pin simplifies IEC 61131-2 short-circuit and overload diagnostics back to the PLC CPU without per-channel ADC channels. The active overload power management and configurable latch-off of the VIPower M0-7 process match the IEC 61131-2 output-fault response expectations, while STMicroelectronics' reverse-battery and load-dump protection survive typical 24 V factory-bus transients.

Power Distribution Boxes and Junction Boxes
Modern automotive power distribution boxes increasingly replace fuses and mechanical relays with smart solid-state switches, and the VND7E050AJTR is one of the load drivers most often mounted on the printed circuit board of these boxes. Each dual 50 A channel can run an entire sub-circuit - for example the rear windshield heater or the trailer socket - returning feedback through the multiplexed current-sense pin to a central CAN/LIN master. Compared with a fuse-and-relay topology, the VND7E050AJTR allows each output's status to be reported on the bus, eliminates service-bay fuse replacement, and supports remote reset via the FaultRST pin. The VIPower M0-7 process provides load-dump robustness that fuses cannot match, lowering warranty cost for transient failures.

설계 노트
Estimated: At full 50 A continuous per channel on both outputs of the VND7E050AJTR, Ron losses alone can exceed 5 W per channel (Ron * I^2). With the PowerSSO-16 thermal resistance of approximately 25 C/W on a 2 oz 4-layer copper-pour PCB, the junction temperature can rise well above 150 C at 25 C ambient. Provide at least 1 sq inch of top-side copper-pour area per channel and use thermal vias to the inner layers. For designs approaching the 50 A rating on both channels, an external aluminum substrate or PCB-side cooling fin is required to keep Tj below 150 C.
Recommended: Use the PowerSSO-16 exposed pad as the primary thermal and electrical ground path - solder it to a copper pour that covers at least 2 sq cm of top-side area with 9 to 16 thermal vias to the inner plane. Place the input capacitors (100 nF CMOS decouplers plus optional 10 uF bulk) within 5 mm of the INx pins to suppress logic-edge di/dt noise. Route CS, FaultRST, and CS_EN as parallel microstrip traces guarded by GND; keep them away from the OUTx high-current traces to avoid load-current cross-coupling into the analog sense amplifier.
Critical: The VND7E050AJTR's analog multiplexed current-sense pin is shared between load current, VCC, and die-temperature diagnostics - the host MCU must service the CS_EN pin to select which signal appears on CS at any given time. If CS_EN is left floating, the CS pin enters an undefined state. Additionally, do not use the FaultRST pin as a simple shutdown; holding FaultRST low during a fault *re-enables* the output, which is the opposite of a normal shutdown input. Plan the firmware fault-clear sequence accordingly.
Optional: Place a TVS diode across the VCC input rated for ISO 7637-2 load-dump waveforms (for example, a SMBJ28CA series clamp) to absorb transient energy outside the VIPower M0-7 absolute-maximum VCC rating. Keep the TVS within 10 mm of the VCC pin so that the loop inductance is minimized. For dual-channel designs, ensure that the OUT1 and OUT2 traces do not share a copper-pour section that could allow thermal cross-coupling between channels during a transient overload event on one side.
