µPD16886
Brush DC Motor Driver
Monolithic 1.5-Chammel H Driver Circuit for Cameras
Overview
The µPD16886 is a monolithic H bridge driver LSI that employs N-channel MOSFETs in its output stage.
This IC incorporates a 1.5-channel H bridge circuit and can control two motors that do not operate at the same time. In addition, forward/reverse, brake, and stop functions are available, making this LSI ideal for driving motors such as the motor for winding the camera film and the lens zoom motor.
Features
- Large output current:
ID(DC) = 1.0 A : During continuous operation
ID(pulse) = 2.8 A : PW <= 20 ms, during single operation
ID(pulse) = 2.2 A : PW <= 200 ms, during single operation - On-chip 1.5-channel H bridge circuit
- Low on-resistance RON = 0.5 Ω max. Sum of the top and bottom on-resistance, total temperature range
- On-chip standby circuit to set the charge pump circuit to OFF
- Low-voltage operation is possible (operable at 2.7 V or higher)
- On-chip undervoltage lockout circuit
- Mounted in a small-scale package 24-pin plastic TSSOP
