LA1638中文资料三洋数据手册PDF规格书

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.

特性 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
