ST L5958SMTR

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. The ignition buffer completes the device. 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.

• 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
• 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, 3.3 V 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.
