Overview
The LB1638, LB1638M are low-saturation bidirectional motor driver ICs for use in low-voltage applications. At an IO of 500mA, they have a low saturation output of VO(sat) = 0.75V. They are especially suited for use in compact motor of portable equipment.
Features
⢠Low voltage operation (2.5V min.)
⢠Low saturation voltage (upper transistor + lower transistor residual voltage; at IO = 500mA, VO(sat) = 0.75V typ.)
⢠Low current drain at standby mode (ICCO = 0.1µA typ. or less)
⢠Separate logic power supply and motor power supply
⢠Brake function
⢠Built-in spark killer diodes
