DESCRIPTION
The L9820 High Side Driver realized with Multipower - BCD mixed technology, drives resistive
or inductive loads with one side connected to
ground.
The ENABLEinput is TTL compatibleand a diagnostic outputprovides an indicationof short circuit
and device status (thermal and overvoltage shutdown).Onchip thermal protection and short circuit
protectionare provided.

PIN FUNCTIONS
N. Name Description
1 POWER OUTPUT The deviceis provided with short circuit protection.
4 POWERSUPPLY Supply voltage input.
5 ENABLE INPUT TTL compatible input. High level on thispin meansoutput current ON.
Thelow level voltage switches off the charge pump, the power stage and
thediagnostic outputreducing to the minimum value thequiescent current.
7 GROUND This pin must be connected to ground.
8 DIAGNOSTIC FEEDBACK The diagnostic circuit is active in input high level condition. This output
detects with Tipically 50µs delay at T
=25°C the following faults:
amb
– Overvoltagecondition.
– Thermal shutdown.
– Shortcircuit. The power stage current is internally limited at 1.5A.
Thediagnostic output is active low. The diagnostic delay timeallows to
avoid spurious diagnosys(i.e.: turnON overcurrent, overvoltage spikes etc.).
