TPM8837E-DF4R

Overview

The TPM8837E-DF4R is a dual half-bridge MOSFET driver manufactured by 3PEAK, designed for driving inductive loads such as DC motors, relays, solenoids, and stepper motors. It operates with a supply voltage range of 1.8V to 5.5V and supports load voltages from 2V to 11V. The device delivers an output current of 1A per channel with a typical on-resistance of 1.1 ohms (LS + HS). It features PWM interface control and is housed in an 8-DFN (2x2) package with a bare pad. Operating temperatures range from -40°C to 150°C TJ.

Feature Summary

• Integrated protection mechanisms including over-current limiting, thermal shutdown, short-circuit protection, and under-voltage lockout.
• Designed for efficient control of inductive loads with high noise immunity and robust ESD protection capabilities.
• Compact surface-mount packaging suitable for space-constrained portable and industrial applications.

Applications

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

Procurement Notes

Verify the specific suffix DF4R against the manufacturer's official datasheet to confirm the exact tape-and-reel quantity and pin configuration. Ensure compatibility with the target PCB footprint, specifically the 8-DFN 2x2 package dimensions. Confirm RoHS3 compliance status if required by regional regulations. Cross-reference the ordering number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a low-voltage, single-supply driver is required for small inductive loads. The 1.8V minimum supply voltage makes it suitable for battery-operated devices. Consider the 1A current limit and 1.1-ohm resistance for thermal management in dense layouts. Verify that the 11V load voltage range meets the application's maximum operating requirements.

Part Context
