L5958 Multifunction voltage regulator for car radio Features ■ L5958 six outputs: – 8.5 V @ 200 mA – 5.0 V @ 300 mA – 3.3 V @ 250 mA – 1.8 V @ 350 mA – 3.3 V @ 100 mA standby – 1.8 V @ 100 mA standby ■ 2 A high side driver ■ Reset function ■ VDD core reset function ■ Battery audio warning ■ Battery can warning ■ Ignition comparator ■ Load dump protection ■ Thermal shutdown ■ Overcurrent limitation ■ All pin ESD protected Flexiwatt27 (vertical) Flexiwatt27 (SMD) The two 3.3 V (REG5) and 1.8 V (REG6) stand-by regulators can reach a quasi-zero current consumption when switched off. The device is equipped with two different reset buffers to control the operating voltages: the reset which checks the two stand-by outputs, 3.3V and 1.8 V, and the VDD core reset which checks the linear switched outputs, 3.3 V and 1.8 V. It is also equipped with two different battery voltage warnings, provided by the Hold CAN and the Hold audio detectors, with the possibility to program the lower threshold through an external resistance. Description The ignition buffer completes the device. The L5958 includes 6 linear voltage regulators and a 2 A power switch, working down to 4.5 V battery level. All the voltage regulators can be switched off through the three enable pins. A backup function is available through two pins which needs to be connected to two independent capacitors: one for the 3.3 V and 1.8 V linear switched outputs and one for the 3.3 V and 1.8 V standby outputs.
