TLE94003EPXUMA1 개요
A DC motor driver (also called a motor driver IC or half-bridge driver) is a power-management semiconductor that sits between a low-power microcontroller and a high-current motor load. Within the power-management IC hierarchy, the TLE94003EPXUMA1 belongs to the broader category of motor drivers > motion controllers > integrated power switches. By integrating three half-bridges, one chip can drive a single three-phase brushless DC (BLDC) motor, three independent brushed DC motors, or be paralleled into full-bridge configurations for higher-current brushed motors.
Key features include 5.5V to 20V supply range, integrated charge pump allowing 100% duty-cycle operation, ultra-low quiescent current in standby, built-in over-current, over-temperature, under-voltage, and short-circuit protection, plus a diagnostic feedback pin. The DMOS output stages are optimized for low on-resistance, which directly minimizes conduction losses and improves thermal performance. The PG-TSDSO-14 package with exposed thermal pad enables efficient heat dissipation in space-constrained automotive modules.
Typical applications include automotive body electronics (HVAC flaps, mirror adjustment, seat positioning), industrial automation (small brushed and brushless DC motors, valve control), and consumer appliances. The integrated protection set eliminates the need for many external components, simplifying PCB layout and reducing BOM cost.
When designing with this part, observe the exposed-pad PCB layout recommendations: solder the thermal pad to a copper pour of at least 1 cm² for proper heat removal. Use decoupling capacitors rated for the full supply transient range, and configure the SPI/EN/diagnostic pins per the datasheet's typical application circuit to ensure correct fault propagation.

일반적인 애플리케이션
TLE94003EPXUMA1 적합 용도: 6 애플리케이션s: Automotive HVAC Flap Actuators, Power Side Mirror and Seat Positioning, Small Three-Phase Brushless DC Motors, Solenoid and Valve Control, DC Brushed Motor Driver for Robotics and Toys, Relay and Lamp Driver Modules.
Automotive HVAC Flap Actuators
The TLE94003EPXUMA1 fits automotive HVAC flap actuators because its 5.5V to 20V supply covers 12V body rails including cold-crank and load-dump transients, and its three independent half-bridges drive the small brushed DC gear-motors that move mode, temperature, and recirculation doors. AEC-Q100 qualification, integrated over-temperature and short-circuit protection, and the 14-pin PG-TSDSO footprint allow compact PCB integration inside the actuator housing. The integrated charge pump supports 100% duty cycle for stall-current startup without requiring an external bootstrap circuit. Design note: pair each output with a 100nF ceramic decoupling cap local to the IC, and solder the exposed pad to at least 1 cm² of copper for thermal relief during continuous stall.

Power Side Mirror and Seat Positioning
Mirror fold/adjust and seat-position modules typically use two to three small brushed DC motors, which the TLE94003EPXUMA1 drives directly via its three half-bridges - one per motor - using parallel logic inputs from the body controller. The DMOS output stages deliver the torque needed for mirror X/Y adjustment and seat rail movement, while the -40 C to +150 C junction range and AEC-Q100 qualification match under-hood and cabin thermal profiles. Built-in over-current protection shuts down safely if a motor stalls at end-of-travel, preventing PCB trace damage. The exposed-pad PG-TSDSO-14 package fits behind the mirror glass or under the seat trim. Compared to discrete MOSFET half-bridges, this part saves roughly 6 to 9 external components per channel, reducing BOM cost and PCB area.

Small Three-Phase Brushless DC Motors
Three independent half-bridges can be combined with external commutation logic to drive small 3-phase BLDC motors used in fans, pumps, and small appliances. The TLE94003EPXUMA1's integrated charge pump keeps the high-side FETs fully enhanced at 100% duty cycle, allowing low-RDSon synchronous rectification that improves efficiency versus external-bootstrap discrete designs. Each half-bridge's diagnostic feedback pin lets the MCU detect desaturation or short-circuit events and shut down safely. The 5.5V to 20V supply covers both 12V automotive and 24V industrial motor systems. For higher-power BLDC applications, two TLE94003EPXUMA1 ICs can be paralleled or the family can be upgraded to a higher-channel SPI variant like the TLE94112ES.
추천
Solenoid and Valve Control
Industrial and process-control solenoid valves typically need bidirectional drive for latching and proportional control, which the TLE94003EPXUMA1's half-bridges provide natively - one half-bridge can drive a single solenoid in both polarities, or two half-bridges can control a proportional valve with H-bridge topology. The integrated over-current limit protects the solenoid windings from inrush transients, while under-voltage lockout prevents partial activation during supply brownouts. The 14-pin PG-TSDSO exposed-pad package allows dense PCB layouts in multi-valve manifolds. Compared to electromechanical relays, the TLE94003EPXUMA1 is silent, has no moving contact wear, and supports PWM current profiling for soft-start and energy-saving hold currents.

DC Brushed Motor Driver for Robotics and Toys
Battery-powered robotics, consumer toys, and small appliances use brushed DC gear-motors that the TLE94003EPXUMA1 can drive directly from a 2S to 4S Li-ion pack (7.4V to 16.8V nominal, within the 5.5V to 20V supply range). The three half-bridges can run three independent drive motors or be combined into one full-bridge for bidirectional control of a single high-current motor. Integrated protection prevents the IC from latching up when a stalled gear-motor pulls inrush current, and the DMOS outputs' low RDS(on) extends battery runtime. The exposed-pad package is small enough for tight robotic enclosures while still dissipating motor inrush heat. For cost-sensitive consumer designs, the part replaces 3 discrete H-bridges with one IC.
추천
Relay and Lamp Driver Modules
Body electronics modules often drive automotive relays (horn, fog lamps, headlamp leveling) and incandescent or LED lamp loads. The TLE94003EPXUMA1's half-bridges can be reconfigured as high-side or low-side switches by holding one side always on, giving flexibility for both lamp and relay drive topologies. Inrush current limiting and over-temperature shutdown protect against the cold-filament surge of incandescent lamps and the back-EMF spike of relay coils. The 5.5V to 20V supply tolerates automotive load-dump transients up to the part's absolute maximum rating. Built-in diagnostic feedback allows the body controller to detect open-circuit lamp filaments without extra wiring, a feature required by some OEM Body Control Module specifications.

설계 노트
Estimated: at VS=14V driving a stalled brushed DC motor pulling 3A through one half-bridge, dissipation is roughly (14V-EMF)*3A. At full stall, worst-case dissipation lands near 30W on a single channel - the exposed pad MUST be soldered to at least 1 cm² of 2 oz copper on a 4-layer board, or the junction will exceed 150 C and trigger thermal shutdown. For multi-motor continuous operation, derate by 30-40% or split loads across channels.
Place a 100nF ceramic decoupling capacitor directly between VS and GND, within 2 mm of the IC pins, to suppress supply transients from motor commutation. Add a 10uF bulk electrolytic or tantalum on the VS rail near the IC for load-dump energy absorption. Route the three OUT traces as short and wide as possible (>= 1 oz copper, 0.5 mm width per ampere) and keep them away from the IN logic traces to avoid dv/dt coupling into the control signals.
Estimated: do not float the EN pin - it must be tied high (logic-level high) for the outputs to enable. Leaving it disconnected puts the part in an undefined state. Also, the exposed thermal pad is the main heatsinking path; if left unsoldered, the part will thermally throttle at much lower currents. Finally, do not exceed 20V on VS for extended periods; the part is rated for short load-dump transients but not continuous over-voltage.
Route the ground return directly under the OUT traces back to the bulk capacitor ground, forming a tight loop. This minimizes parasitic inductance that can cause VS over-voltage spikes during motor commutation (>50V peaks are common if the loop is poorly laid out). Place the DIAG trace away from switching nodes, or shield it with a grounded trace, to prevent false fault triggers from capacitive coupling.
