LB1934T Datasheet 3v Camera 1.5-channel Driver

Manufacturer: SANYO (now Panasonic)

Overview: 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 control signals. The 0.5-channel section of the 1.5channel bridge can be divided into sink/source output, allowing configurations such as 1-channel bridge + sink output + source output. Package Dimensions unit:mm 3246-TSSOP20 [LB1934T] 20 11 0.5 4.4 6.4 0.08 (1.0) 1.2max 6.

Key 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.
  • Zero power dissipation in standby mode.
  • Direct microcontroller drive possible (any strength relationships of voltage supported between microcontroller control signal and VCC or V.
