LB1934 3V Camera 1.5-Channel Driver

Ordering number:ENN6195A Monolithic Digital IC LB1934T 3V Camera 1.5-Channel Driver Overview The LB1934T is a low-voltage, low-saturation forward/ reverse driver IC with built-in 1.5-channel bridge. Its compact, low-profile package makes it ideal for use in compact cameras powered by 3V lithium batteries. Using direct microcontroller drive, it is possible to control standby, forward rotation, reverse rotation, and braking of two motors for film rewind and lens drive by means of only three cont.

LB1934 Features

* Low voltage drive possible. When using same power supply for V CC and V S : VCC=VS=1.4V min. When using separate power supply for VCC and VS : VS=1.0V min., VCC=1.4V min.

* Low saturation voltage : residual voltage (upper side transistor + lower side transistor) =0.5V typ. at Io=1A
