About Motor Driver ICs

Motor driver integrated circuits act as the critical interface between low-power control signals (from microcontrollers) and high-power motors. They efficiently convert logic-level commands into precise voltage/current outputs while handling back-EMF and inductive loads. Without dedicated drivers, motors risk underperformance, overheating, or controller damage due to electrical noise and power mismatches.

Modern motor drivers like the DRV8835 series integrate control logic, power stages, and protection features into single-chip solutions. This consolidation reduces PCB footprint, simplifies design complexity, and enhances system reliability—particularly vital for battery-dependent devices where energy conservation and thermal management are paramount.

FAQs

Q: Can this IC drive both DC and stepper motors?
A: Yes, it supports brushed DC motors and bipolar stepper motors via its dual H-bridge configuration.

Q: What protection features are included?
A: Integrated safeguards include thermal shutdown, under-voltage lockout, and overcurrent protection.

Q: Is a heat sink required for 1.5A operation?
A: The exposed thermal pad provides sufficient dissipation for most applications at full load, but PCB copper pours are recommended.

Q: How does this differ from the DRV8835 model?
A: DRV8835DSSR is the specific WSON package variant; base functionality aligns with the DRV8835 series.

Q: Can I use this with 3.7V Li-ion batteries?
A: Absolutely—its 2V–7V supply range makes it ideal for single or dual-cell Li-ion applications.

Q: Are evaluation modules available?
A: Texas Instruments offers the DRV8835EVM development board; contact PCX for compatible accessories.
