L9820 HIGH SIDE DRIVER ADVANCE DATA OPERATING SUPPLY VOLTAGE UP TO 25V DC CURRENT 0.3A RON < 800mΩ DIAGNOSTIC AND PROTECTION FUNCTIONS µP COMPATIBLE ENABLE INPUT FOR STAND-BY MODE DESCRIPTION The L9820 High Side Driver realized with Multipower - BCD mixed technology, drives resistive or inductive loads with one side connected to ground. The ENABLE input is TTL compatible and a diagnostic output provides an indication of short circuit and device status (thermal and overvoltage shutdown). Onchip thermal protection and short circuit protection are provided.

Name 1 POWER OUTPUT The device is provided with short circuit protection. 4 POWER SUPPLY Supply voltage input. 5 ENABLE INPUT 7 GROUND 8 DIAGNOSTIC FEEDBACK Description TTL compatible input. High level on this pin means output current ON. The low level voltage switches off the charge pump, the power stage and the diagnostic output reducing to the minimum value the quiescent current. This pin must be connected to ground. The diagnostic circuit is active in input high level condition. This output detects with Tipically 50µs delay at Tamb = 25°C the following faults: – Overvoltage condition. – Thermal shutdown. – Short circuit. The power stage current is internally limited at 1.5A. The diagnostic output is active low. The diagnostic delay time allows to avoid spurious diagnosys(i.e.: turn ON overcurrent, overvoltage spikes etc.).
