Monolithic Digital IC 3V Camera 1.5-Channel Driver Ordering number:ENN6195A LB1934T SANYO Electric Co.,Ltd. Semiconductor Company TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN 12502TN (KT)/62599RM (KI) No.6195–1/6 0.65 (0.33) 0.22 0.15 6.5 1 10 20 11 Package Dimensions unit:mm 3246-TSSOP20 [LB1934T] SANYO : TSSOP20 Overview The LB1934T is a low-voltage, low-saturation forward/ reverse driver IC with built-in 1.5-channel bridge. Its com- pact, 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 1.5- channel bridge can be divided into sink/source output, al- lowing configurations such as 1-channel bridge + sink out- put + source output. Features • Low voltage drive possible. When using same power supply for VCC and VS : 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 tran- sistor + lower side transistor) =0.5V typ. at Io=1A. • Zero power dissipation in standby mode. • Direct microcontroller drive possible (any strength rela- tionships of voltage supported between microcontroller control signal and VCC or VS). • Logic power supply and motor power supply can be sup- plied at separate pins. • Built-in thermal protection circuit. • Number of control signals can be optimized for the set. “2-motor control” or “1-motor + 2-load control” can be implemented by 3 control signals. In addition to the above, 4 control signals allow implemention of a “input ignore mode” where two con- trol signals are used in conjunction with other IC input signals. • Built-in spark killer diode. • Compact, low-profile package (TSSOP-20 ; thickness=1.1 mm typ.) |
