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.

Recommended output filtering capacitors for all the regulators: C range = 5 µF to 100 µF,
ESR range = 50 m to 10 (T= -40 °C to +85 °C)
The detection voltage thresholds (for both the battery warning 1 and 2) can be changed
lower with external resistors, as following:
VTH1(hold_can) = 1.25V (R3 + R4)/ R4
VTH2(hold_audio) = 1.25V (R1 + R2)/R2
