Voltage regulator with backup and reset, overvoltage protection and low voltage warning
L4954 is a quad output voltage regulator and a three output high side driver.
The IC includes monitoring circuitry to warn the microprocessor of a low voltage condition: the LVWarn, output, sensing the slow dropping of STCAP pins voltage, gives the microprocessor time to store data.
A reset output is generated at REG4’s decay.
External protection must be provided for reverse battery protection.
