TPM8837C-DF4R

Overview

The TPM8837C-DF4R is a dual half-bridge motor driver manufactured by 3PEAK, designed for driving DC motors, relays, solenoids, and stepper motors. It utilizes NMOS technology and features an 8-DFN (2x2) exposed pad package. The device operates with a supply voltage range of 2.5V to 17V and supports a continuous output current of 1A per channel. It has a typical on-resistance of 850mOhm for the low-side and high-side MOSFETs combined. The component supports PWM interface control and includes comprehensive protection features such as current limiting, over-temperature shutdown, short-circuit protection, ESD protection, and under-voltage lockout (UVLO). It functions within an ambient temperature range of -40°C to 125°C.

Feature Summary

• Dual half-bridge configuration enabling independent control of two loads or H-bridge operation
• Integrated NMOS power stage with low on-resistance for efficient drive capability
• Comprehensive fault protection including current limiting, thermal shutdown, and short-circuit detection
• Supports PWM input signals for precise speed and direction control

Applications

• DC motor control systems
• Relay driver circuits
• Solenoid actuation
• Stepper motor drivers

Procurement Notes

Verify the exact suffix 'DF4R-S' against the manufacturer's official datasheet to confirm pinout and electrical specifications match your design requirements. Ensure the 8-DFN package footprint aligns with your PCB layout guidelines. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the specific revision level to avoid compatibility issues with existing designs.

Selection Notes

Select this component when a compact dual half-bridge solution is needed for low-power inductive loads. It is suitable for applications requiring a wide supply voltage range up to 17V. Consider the 850mOhm total resistance for efficiency calculations. The exposed pad package requires careful thermal management on the PCB. Verify that the 1A current rating meets the peak and continuous load requirements of the target application.
