L5959 STMicroelectronics

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) Multiwatt15 Two protected high side driver (HSD1, HSD2) Reset function Battery voltage (under/over) warning output Description Load dump protection Independent thermal shutdown on all The L5959 contains a four voltage regulator and regulators and HSDs two protected HSDs. HSDs are protected against loss of ground and loss of battery. Overcurrent limitation Storage CAP output (STCAP) The IC includes a monitoring circuit for detection. Small CAP required by stability of regulators The IC features a very low quiescent current in stand-by and independent thermal shutdown. All pins ESD protected Table 1.
