BTM9020EPXUMA1 Overview
A brushed DC motor driver is an integrated power stage that switches the polarity of voltage across a DC motor winding to control direction, speed, and torque. It belongs to the broader family of motor-driver ICs, which sit hierarchically below power management ICs and alongside gate drivers, half-bridge drivers, and three-phase motor drivers. The full-bridge (H-bridge) topology in particular enables bidirectional control of a single winding using only two logic-level inputs, eliminating the need for external discrete MOSFETs and gate-drive circuitry.
Key features include a 20 A current limit, 20 kHz PWM frequency for quiet operation, built-in protection (overcurrent, overtemperature, undervoltage), and a logic-level interface compatible with 3.3 V and 5 V microcontrollers. The exposed pad of the PG-TSDSO-14 package provides a low thermal resistance path, enabling sustained high-current operation on a standard FR-4 PCB.
Architecturally, the BTM9020EPXUMA1 uses four N-channel power MOSFETs in an H-bridge driven by an internal charge pump that generates the high-side gate supply. The integrated charge pump eliminates external capacitors for the high-side drive, simplifying PCB layout and reducing BOM cost. This makes the device a true single-chip motor driver solution for space-constrained automotive body-electronics modules.
Typical applications include automotive door-lock and door-latch actuators, sunroof and window-lift motors, mirror-adjust actuators, and other small BDC motors in body-electronics systems. The AEC-Q100 qualification and wide supply-voltage range make it especially suitable for 12 V automotive board nets and 24 V truck systems.
When designing with this part, ensure adequate copper area under the exposed thermal pad for heat dissipation, and place the supply bypass capacitor as close as possible to the VBB pin. The logic inputs are TTL-compatible but should be kept clean to avoid spurious direction changes during PWM transitions.

Typical Applications
BTM9020EPXUMA1 is suitable for 6 applications: Automotive Door Lock Actuator, Door Latch and Cinch Motor, Sunroof and Window Lift Motor, Power Mirror Adjuster, Trunk Lift and Tailgate Actuator, HVAC Flap and Blower Motor.
Automotive Door Lock Actuator
The BTM9020EPXUMA1's 84 mΩ typical path resistance and 20 A current limit make it well suited to drive door-lock actuators in 12 V automotive board nets. Placed between the battery rail and the lock motor, the full-bridge H-bridge topology enables bidirectional control from a single chip, eliminating external MOSFETs and gate drivers. With 20 kHz PWM operation, motor commutation noise stays above the audible band, ensuring cabin quietness. AEC-Q100 qualification confirms reliability for the lifetime of the vehicle.
Recommended
Door Latch and Cinch Motor
Door-latch and cinch motors require short high-current bursts to pull the latch into position; the BTM9020EPXUMA1 supports 8.8 A pulses for ≤ 1 s at 85 °C, which directly meets this profile. The integrated current limit at 20 A protects the motor winding during mechanical stall, while the extended 40 V supply rating covers ISO 7637-2 jump-start transients. Its PG-TSDSO-14 package with exposed thermal pad enables a 4-layer FR-4 PCB to dissipate the latch pulse without heatsinking.
Recommended
Sunroof and Window Lift Motor
Sunroof and window-lift motors demand sustained bidirectional torque; the BTM9020EPXUMA1's 6.9 A continuous rating at ≤ 10 s pulse covers the worst-case stall window. The integrated charge pump generates the high-side gate supply without external capacitors, simplifying the PCB and reducing BOM cost. The 7-18 V nominal supply matches the 12 V automotive board net exactly, and logic-level inputs interface directly to 3.3 V body controllers without level shifters.
Recommended
Power Mirror Adjuster
Power-mirror adjusters use small BDC motors that require compact, low-Rdson drivers; the BTM9020EPXUMA1's 84 mΩ path resistance keeps conduction losses under 0.5 W per phase at 3 A load. The PG-TSDSO-14 footprint is small enough to fit inside the mirror housing PCB, and the integrated protection suite eliminates the need for external fuses or PTCs. The 20 kHz PWM frequency keeps mirror-adjust operation inaudible to the driver.
Recommended
Trunk Lift and Tailgate Actuator
Trunk-lift and tailgate actuators need high torque to overcome spring preload; the BTM9020EPXUMA1's 20 A current limit and 8.8 A pulse capability drive actuators with significant mechanical load. The integrated overtemperature shutdown protects the IC during stalls, while the 4.5-40 V extended supply rating handles 24 V truck-board-net vehicles and cold-crank voltage drops to 6 V on cold mornings. AEC-Q100 grade-1 qualification confirms -40 °C to +125 °C operation.
Recommended
HVAC Flap and Blower Motor
HVAC flap and small blower motors benefit from the BTM9020EPXUMA1's PWM speed-adjust capability and full-bridge direction control. The 20 kHz PWM input allows soft-start profiles that reduce acoustic noise on flap transitions. Integrated undervoltage lockout prevents malfunction during cranking, and the exposed thermal pad of PG-TSDSO-14 supports sustained operation at moderate current levels in the HVAC housing.

Key Differentiators
- Single-chip full-bridge with integrated charge pump (vs BTM9021EPXUMA1)

- 40 V extended supply rating (vs TLE94104EPXUMA1 / TLE94110ESXUMA1)
Design Notes
Estimated: at 5 A continuous output current with 84 mΩ path resistance, conduction loss is approximately 5² × 0.084 = 2.1 W. The PG-TSDSO-14 package requires at least 1 square inch of 1 oz² copper on the top layer plus thermal vias to the inner layers to keep junction temperature rise below 50 °C. For sustained operation above 6 A, add an exposed pad copper pour of 4 square inches. Estimated junction rise assumes 30 °C/W theta_JA on a 4-layer JEDEC test board.
Place a 100 nF ceramic bypass capacitor as close as possible to the VBB pin (within 3 mm). Add a bulk electrolytic or tantalum capacitor of at least 47 µF on the supply rail to absorb motor back-EMF. The exposed thermal pad (EP) must be soldered to a copper pour with a via array (typical 4×4 0.3 mm vias) for thermal dissipation. Keep logic input traces short and routed away from OUT1/OUT2 switching nodes to avoid capacitive coupling.
Do not apply reverse polarity to VBB - the BTM9020EPXUMA1 does not include reverse-battery protection. Add an external Schottky diode or P-MOSFET reverse-polarity circuit if the application requires jump-start with reversed jumper cables. Also, do not exceed 40 V on VBB even transient - although the device is rated for 40 V extended operation, sustained overvoltage will trigger thermal shutdown.
