X40421S14-BT1

The X40421S14-BT1 is a PMIC (power management integrated circuit) supervisor that is used for power supply sequencing control of system level applications. It is used for a variety of applications that include mobile phones, laptops, electronic consumer units, and portable electronic products. The X40421S14-BT1 is designed to detect overvoltage and undervoltage faults and to provide the necessary reset functionalities in response to them such as resetting of system level voltage regulator and digital logic.

The X40421S14-BT1 Supervisors provide an easy-to-use programmable power supervising solution. It is equipped with an 8-bit programmable supply control register, an 8-bitprogrammable reference control register, an 8-bit programmable trim control register, and a 32-bit programmable memory. The supervisor supports input voltages ranging from 1.4V to 7V and 5V or 3.3V output.

The X40421S14-BT1 Supervisors provide a single, programmable supply input, an adjustable supply enable, and low power reset output. It provides an adjustable supply enable to enable power management sequencing of multiple supplies. The supervisor also has an adjustable supply enable that is used to limit inrush current and an adjustable current latch timer to ensure a guaranteed reset time. The ring oscillator configuration provides an adjustable oscillator frequency for maximum system stability.

The X40421S14-BT1 Supervisors also provide a Power-On Reset (POR) output and an adjustable reset monitor output. The POR output provides a reset signal to the system on power-up. The reset monitor output is used to monitor the voltage drop of the system reset. The adjustable reset monitor output is used to verify the reset operation of the system. The adjustable threshold settings can be used to detect and recover from various overvoltage and undervoltage conditions.
