Overview
Ordering number : EN3517A Monolithic Digital IC 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).
