Description

The L5959 contains a four voltage regulator and two protected HSDs. HSDs are protected against loss of ground and loss of battery.

The IC includes a monitoring circuit for detection.

The IC features a very low quiescent current in stand-by and independent thermal shutdown.

Features

■ Four outputs

– 8.5V @ 200mA (V8P5)

– 8/10V @ 1000mA selectable 10V or 8V (V810)

– 3.3V @ 100mA permanent (VSTBY)

– 3.3V @ 800mA (VREGSW)

■ Two protected high side driver (HSD1, HSD2)

■ Reset function

■ Battery voltage (under/over) warning output

■ Load dump protection

■ Independent thermal shutdown on all

regulators and HSDs

■ Overcurrent limitation

■ Storage CAP output (STCAP)

■ Small CAP required by stability of regulators

■ All pins ESD protected
