LB8649FN-MPB-E

Overview

The LB8649FN-MPB-E is a monolithic digital IC motor driver designed for digital still cameras (DSCs). It integrates actuator drivers on a single chip, featuring constant current outputs for stepping motors used in SH/AE or VCM functions, and constant voltage outputs for ZOOM, DC motors, or AF actuators. The device supports independent power supplies for four systems: SH/AE, AF, ZOOM, and input logic. It enables low-voltage driving using two nickel hydride batteries and includes built-in thermal protection circuitry.

Feature Summary

Integrates constant current and constant voltage output channels for various camera actuators on a single chip
Supports independent power supply systems for SH/AE, AF, ZOOM, and input logic circuits
Features zero standby current consumption allowing direct battery connection
Includes built-in thermal protection circuitry for operational safety

Applications

Actuator drivers for digital still cameras
Stepping motor control for SH/AE or VCM functions
DC motor driver for zoom mechanisms
AF actuator control

Procurement Notes

Verify the specific suffix MPB-E against the manufacturer's official documentation to confirm package type and pinout compatibility. Ensure the sourcing channel provides valid datasheets from Sanyo Semiconductor or authorized successors. Confirm that the component meets the required operating temperature range and voltage specifications for the target application before procurement.

Selection Notes

Select this component for applications requiring integrated control of multiple camera actuators with minimal external components. It is suitable for designs needing low standby current and direct battery operation. Verify that the load requirements for SH/AE, AF, and ZOOM channels align with the device's constant current and voltage output capabilities.

Part Context

This part belongs to the LB8649 series of motor drivers manufactured by Sanyo Semiconductor. These devices are specialized for consumer electronics, particularly digital imaging equipment. The series focuses on integrating multiple drive functions into a compact form factor to reduce board space and component count in portable devices.
