BTN9990LVAUMA1 Overview
A half-bridge is a power-electronics topology that switches a load between a high-side supply rail and ground using two MOSFETs in a push-pull arrangement; the half-bridge is the building block of H-bridge DC motor drivers, three-phase BLDC inverters, and synchronous buck converters. By integrating the power stage into a single exposed-pad package, the BTN9990LVAUMA1 reduces PCB area, simplifies thermal design, and minimizes parasitic loop inductance that otherwise causes voltage overshoot during switching.
Key features of the BTN9990LVAUMA1 include integrated charge-pump for 100% duty-cycle high-side operation, under-voltage lockout (UVLO) on both the logic and gate-drive supplies, over-current protection, and an exposed thermal pad that delivers a low thermal resistance to the PCB copper pour. Logic-level inputs interface directly to 3.3 V or 5 V microcontrollers, eliminating the need for external level shifters in most 12 V automotive applications.
Typical applications include brushed DC motor control in automotive body modules (window lift, seat adjustment, tailgate), industrial relay and solenoid replacement, LED driver power stages, and small BLDC half-bridge stages where each phase is built from two of these parts. The exposed-pad package allows the heat of the switching losses to be conducted directly into the PCB copper, removing the need for an external heatsink in most well-designed boards.
When designing with this device, follow Infineon's PG-HSOF-7-1 PCB layout recommendations: place input and motor ceramic bypass capacitors as close to the package as possible, and provide at least 6 cm² of 2 oz copper on the opposite side of the board tied to the exposed pad. The motor supply (VS) and logic supply (VCC) should be decoupled separately to prevent logic reset during motor current transients.

Typical Applications
BTN9990LVAUMA1 is suitable for 6 applications: Automotive Window Lift Motor, Power Seat Adjustment Drive, Industrial Solenoid and Valve Driver, Tailgate/Liftgate Power Actuator, LED Driver Power Stage (High-Current), Small BLDC Motor Half-Bridge Stage.
Automotive Window Lift Motor
The BTN9990LVAUMA1's 60 V load rating and AEC-Q100 qualification make it well-suited to drive 12 V brushed DC window-lift motors in body control modules. Two devices form a full H-bridge that reverses polarity to raise and lower the window, with the integrated dead-time and shoot-through protection preventing cross-conduction during direction changes. The PG-HSOF-7-1 exposed-pad package conducts motor-stall dissipation into the PCB copper, eliminating external heatsinks. Load-dump transients up to 40 V on the VS rail are tolerated within the 60 V abs-max envelope. The 5 V VCC and 3.3 V-compatible inputs interface directly to the body-control MCU without level shifters.
Recommended
Power Seat Adjustment Drive
Power seat motors draw 10-30 A peak during recline and fore/aft adjustment, well within the BTN9990LVAUMA1's integrated MOSFET capability when two devices are configured as an H-bridge. The integrated charge pump maintains high-side enhancement at 100% duty cycle, which is essential for the slow-decay current-control loops used in seat position servoing. AEC-Q100 Grade 1 qualification and the -40 C to +150 C junction range cover the under-seat thermal environment. The 60 V VS abs-max protects against the load-dump pulses common in seat-wiring harnesses. The PG-HSOF-7-1 single-package solution reduces PCB area versus discrete MOSFET + driver designs.
Recommended
Industrial Solenoid and Valve Driver
The BTN9990LVAUMA1 is an efficient replacement for bulky electromechanical relays in 24 V industrial solenoid and valve applications, switching loads up to 60 V without contact bounce or coil-induced back-EMF wear. The integrated over-current and over-temperature protection latches the output off during a stuck-valve fault, eliminating the need for a separate fuse on every solenoid channel. The 5 V logic supply and 3.3 V-compatible inputs allow direct connection to industrial PLC digital outputs or 32-bit MCUs. The PG-HSOF-7-1 package withstands the high-vibration industrial environment when the exposed pad is soldered to a robust copper pour.
Recommended
Tailgate/Liftgate Power Actuator
Power tailgate actuators use brushed DC motors that draw high inrush currents when the gate unlatches. The BTN9990LVAUMA1 handles the inrush within its safe operating area, and the integrated current-limit can be configured to detect a stalled or jammed gate and signal the body controller to abort. The AEC-Q100 qualification matches the harsh thermal and EMC environment in the rear body area. Two BTN9990LVAUMA1 devices in an H-bridge configuration drive the gate motor bidirectionally, with the dead-time protection preventing shoot-through during fast direction reversals triggered by the anti-pinch safety logic.
Recommended
LED Driver Power Stage (High-Current)
The BTN9990LVAUMA1 can be used as the high-current switching element in a high-power LED headlight or work-light driver, where the integrated half-bridge simplifies the buck or boost power stage. The 60 V abs-max VS rating allows direct connection to 12 V and 24 V automotive rails with substantial transient headroom. The low-side switch can be PWM'd at audio frequencies above 100 Hz to dim the LED without audible flicker. The exposed-pad package conducts PWM switching losses into the PCB copper, supporting continuous high-power LED operation without external heatsinks.
Recommended
Small BLDC Motor Half-Bridge Stage
For small three-phase BLDC motors (such as those in fans, pumps, and e-bike accessories), three BTN9990LVAUMA1 devices form a complete three-phase inverter stage, replacing six discrete MOSFETs and three half-bridge driver ICs. The integrated charge pump and dead-time logic reduce the firmware burden on the motor-control MCU. The AEC-Q100 qualification makes the resulting inverter suitable for automotive water pumps, oil pumps, and cooling fans. The PG-HSOF-7-1 exposed-pad package keeps the inverter footprint small enough to fit inside the motor housing for integrated spindle designs.

Key Differentiators
- Integrated half-bridge in single PG-HSOF-7-1 exposed-pad package (vs Discrete MOSFET + gate driver (e.g., 2x IPD90N10S4L + IRS2003))
- 60 V load supply rating covers 12 V and 24 V automotive buses with load-dump headroom (vs BTN7970 (legacy 25 V max))
- AEC-Q100 qualified with integrated protection (UVLO, OCP, OTP) (vs Generic integrated half-bridges without automotive qualification)
Design Notes
Estimated: At VS=14 V, motor stall current 15 A, the BTN9990LVAUMA1 dissipates approximately (RDS(on) * I^2). With a typical RDS(on) of 10 mOhm per leg, both legs together conduct about 2.25 W at 15 A. Solder the exposed pad to at least 6 cm² of 2 oz copper on the opposite board side; this keeps junction rise below 30 C at room ambient. For continuous high-current applications, increase the copper area or add thermal vias to an internal ground plane.
Place the VS ceramic bypass capacitor (>= 100 nF X7R) within 2 mm of the VS pin, and a bulk electrolytic (>= 47 uF) within 5 mm. Use wide copper pours on VS and GND to minimize parasitic inductance that causes voltage overshoot during switching. The INH and INL traces should be kept short and routed away from the OUT/VS switching node to avoid capacitive coupling that could cause shoot-through. Per Infineon's PG-HSOF-7-1 application note, the exposed-pad thermal land should be at least 6 mm × 6 mm with a 3x3 via array of 0.3 mm thermal vias.
Do not tie VCC and VS together - the 5 V logic supply must remain stable even when the motor supply is removed or transients. Do not exceed 60 V on VS, including load-dump transients; add a TVS diode (e.g., 58 V SMBJ) on VS for 24 V industrial systems. Avoid leaving INH or INL floating - unused inputs should be tied to GND through a 10 kOhm resistor to prevent accidental turn-on. Do not switch the load faster than the datasheet-specified minimum on-time, or the charge pump may not maintain high-side gate enhancement.
