LB1834M
Low-Saturation Bidirectional Motor Driver for Low-
Voltage Applications
Overview
The LB1834M is a low-saturation bidirectional motor driver IC (with brake function) for use in low-
voltage applications. It is especially suited for use in portable equipment such as VCR, camera, radio cassette recorder.
Package Dimensions
unit: mm 3097-MFP16FS
[LB1834M]
Features
2 motors drivable due to on-chip 1.5ch bridge driver of IO=1.0A drive current. Capable of being operated from low
voltage (2.5V min). Low saturation
voltage. Low current dissipation at standby mode. Logic power supply and motor power supply are separate. Brake function (Pins OUT1, OUT2 provide BS terminal for forced brake by external transistors). On-chip spark killer diodes. Compact package (MFP-16FS).
