L9820D STMicroelectronics

L9820 HIGH SIDE DRIVER OPERATING SUPPLY VOLTAGE UP TO 25V MULTIPOWER BCD TECHNOLOGY DC CURRENT 0.3A R < 800m ON DIAGNOSTIC AND PROTECTION FUNC- TIONS P COMPATIBLE ENABLE INPUT FOR STAND-BY MODE DESCRIPTION The L9820 High Side Driver realized with Mul- tipower - BCD mixed technology, drives resistive Minidip SO8 or inductive loads with one side connected to ground. ORDERING NUMBERS: The ENABLE input is TTL compatible and a diag- nostic output provides an indication of short circuit L9820 L9820D and device status (thermal and overvoltage shut- down). Onchip thermal protection and short circuit protection are provided.
