L6204 DMOS DUAL FULL BRIDGE DRIVER SUPPLY VOLTAGE UP TO 48V MULTOPOWER BCD TECHNOLOGY R 1.2 L6204 (25C) DS(ON) CROSS CONDUCTION PROTECTION THERMAL SHUTDOWN 0.5A DC CURRENT TTL/CMOS COMPATIBLE DRIVER HIGH EFFICIENCY CHOPPING Powerdip 16+2+2 SO 24+2+2 MULTIPOWER BCD TECHNOLOGY ORDERING NUMBERS: L6204 L6204D DESCRIPTION The L6204 is a dual full bridge driver for motor control applications realized in BCD technology Each bridge has a sense resistor to control the which combines isolated DMOS power transistors currenrt level. with CMOS and Bipolar circuits on the same chip. The L6204 is mounted in an 20-lead Powerdip and By using mixed technology it has been possible to SO 24+2+2 packages and the four center pins are optimize the logic circuitry and the power stage to used to conduct heat to the PCB. At normal oper- achieve the best possible performance. ating temperatures no external heatsink is re- The logic inputs are TTL/CMOS compatible. Both quired. channels are controlled by a separate Enable.
