Key Features
- 6-channel half-bridge motor driver supporting up to 6 brushed DC motors simultaneously at 2 A per output channel
- SPI interface with 8-bit PWM resolution enables precise microcontroller-driven speed control without external PWM logic
- Integrated over-current, over-temperature, and under-voltage protection reduces external component count and improves system reliability in 12 V automotive environments
Applications
The TLE94112ELXUMA1 is designed for automotive body electronics such as seat position actuators, mirror adjusters, and HVAC blend door motors that require simultaneous independent control of multiple low-power brushed DC motors from a single 12 V rail. Its SPI interface and integrated protection features make it suitable for industrial multi-axis conveyor systems and robotic joint actuators where a single MCU must command up to 6 axes with minimal external circuitry. Smart home appliances including multi-zone valve controllers and motorized window blinds also benefit from its compact SSOP-24 footprint and low quiescent current.

Frequently Asked Questions
How many DC motors can the TLE94112ELXUMA1 drive simultaneously, and what is the per-channel current limit?
The TLE94112ELXUMA1 integrates 6 half-bridge outputs that can drive up to 6 independent brushed DC motors simultaneously, each at a maximum continuous output current of 2 A. Alternatively, pairs of half-bridges can be combined to drive larger loads at up to 4 A per motor, reducing the maximum motor count to 3 in that configuration.
What interface does the TLE94112ELXUMA1 use for microcontroller communication, and what PWM resolution does it offer?
The TLE94112ELXUMA1 uses an SPI serial interface for all configuration and motor control commands. It provides 8-bit PWM resolution internally, allowing 256 discrete speed steps per motor channel. The SPI bus operates at clock frequencies up to 1 MHz, enabling all 6 motor channels to be updated within a 100 µs control cycle from a standard microcontroller.
What protection features are built into the TLE94112ELXUMA1, and how do they reduce external component count?
The TLE94112ELXUMA1 includes integrated over-current protection (OCP), over-temperature shutdown (OTS), and under-voltage lockout (UVLO) on all 6 half-bridge outputs. These features eliminate the need for external current-sense resistors, thermistors, and voltage supervisors in most automotive 12 V motor drive designs, reducing BOM component count by 8–12 passive parts and shrinking the PCB area by approximately 20%.
Can the TLE94112ELXUMA1 drive a bipolar stepper motor, and what current is available for that configuration?
Yes, two pairs of half-bridges on the TLE94112ELXUMA1 can be configured as two full H-bridges to drive a bipolar stepper motor. Each H-bridge delivers up to 2 A per phase, which is sufficient for NEMA 8 to NEMA 14 stepper motors with rated winding currents below 2 A. Microstepping can be implemented in software by updating the SPI-controlled PWM duty cycles for each winding at steps as fine as 1/256 of a full step.
