L5959
Voltage regulator with very low stand-by current, reset, hold, backup, under/over voltage detection, overcurrent limitation
September 2013 Rev 3 1/19
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
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.
