Global Mixed-mode Technology G2057/G2057A Full-Bridge PWM Motor Driver Features General Description H-Bridge Motor Driver The G2057/G2057A provides a versatile motor driver Low Typical R MOSFETs (0.6 HS+LS) solution with a variety of capabilities. The device con- DS(on) Low-Power Sleep Mode tains a full H-bridge which can be used to drive a 100% PWM Supported brushed DC motor, one winding of a stepper motor, or 6.5V to 40V Operating Supply Voltage Range other devices such as solenoids. Two logic inputs pro- Protection Features: vide directly interfacing to controller circuits. - VBB Undervoltage Lockout (UVLO) - Overcurrent Protection (OCP) The output stages use four N-channel power MOSFETs - Short-to-Supply Protection configured as an H-bridge. The G2057/G2057A capa- - Short-to-Ground Protection ble of peak output currents up to 3.5A and operating - Over-temperature Shutdown Protection (OTS) voltages up to 40V. - Fault Condition Indication Pin (nFAULT) A low-power standby mode is provided which shuts down internal circuitry to achieve a very low quiescent current draw. Applications Printers The G2057 device features an adjustable PWM current Industrial Automation limit at VSEN pin. And G2057A provided a fixed current Robotics limit 0.35V. Internal protection functions are provided for undervol- tage(UVLO), overcurrent(OCP), short-to-supply, short-to-ground, and overtemperature(OTS). Fault con- ditions are indicated through the nFAULT pin. The G2057 and G2057A are both packaged in SOP-8 (FD)package. Ordering Information ORDER TEMP.
