DRV8212DRLR H-Bridge Motor Driver SOT-563

DRV8212DRLR H-Bridge Motor Driver SOT-563 is a highly integrated, low-power integrated circuit designed specifically for controlling brushed DC motors and solenoid actuators in compact electronic applications. Operating over a wide voltage supply range of 1.65 V to 11 V, this low-voltage motor driver provides precise bidirectional control while drawing minimal quiescent current. Consequently, engineers frequently select this IC for battery-powered applications where board space and power efficiency remain critical design constraints. Furthermore, Texas Instruments engineered the driver with an N-channel power MOSFET H-bridge stage capable of delivering up to 4 A peak output current. Therefore, designers can easily interface low-voltage microcontrollers directly to high-current loads without requiring auxiliary discrete transistor circuitry.

Key Features:

• Wide Operating Voltage: Supports input supplies from 1.65 V up to 11 V, making it versatile for multi-cell alkaline or single-cell Li-ion battery designs.
• High Current Output: Delivers continuous driving current while safely delivering peak pulse currents up to 4 A.
• Ultra-Compact SOT-563 Package: Minimizes overall Printed Circuit Board footprint, which allows seamless integration into space-constrained wearable or portable gear.
• Integrated Protection Features: Incorporates robust internal protection mechanisms against undervoltage lockout, overcurrent events, and thermal shutdown.
• Low On-State Resistance: Features a remarkably low RDS(ON) value, consequently reducing heat dissipation and maximizing system battery lifespan.
