L5959
Multifunction voltage regulator for car radio
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
Multiwatt15
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.
