X40021S14Z-A Application Field and Working Principle

The X40021S14Z-A is a fully integrated supervisor IC from the range of power management ICs (PMIC) designed for reset applications. It is designed for quick and easy reset operations should sudden power glitches or system crashes occur, effectively protecting a system from unexpected power shut-downs and malfunctions. The X40021S14Z-A is a small-size, highly reliable IC that offers numerous advantages over other existing power management ICs (PMICs).

The main application field of the X40021S14Z-A lies in industrial systems, robots, automotive applications and healthcare technology. It has the capability to monitor low voltage levels and reset according to set conditions, prevents the system from crashing by providing a reset pulse. The IC has a small 6-pin SOT package, which makes it suitable for various application fields with limited space.

The X40021S14Z-A works by monitoring battery and system voltages, then generating a reset signal when the voltage falls below a set threshold. The IC can detect low voltages in two different supply networks and offer a boosted output voltage in low voltage Operating mode thus increasing the efficiency of the system. It also has an extended reliability rating at high temperature and is designed for I²C communication for easy integration and monitoring.

When the voltages and currents change, the X40021S14Z-A can adjust its reset behavior in realtime. It is able to detect and offer low-voltage notification, watchdog reset and over-temperature protection. The IC operates in the temperature range of -40°C - +125°C, making it highly reliable in the most extreme temperature environments.

The X40021S14Z-A provides a reset pulse at a duration of 10ms, which is adjustable with external capacitor and hence can be extended to 100ms. The reset/assert level of the IC is set at 2.6V and is adjustable from 1.15V to 3.0V. The minimum pulse width of the IC is 1ms and the input voltage range is from 2V to 6V.

In summary, the X40021S14Z-A is an ideal IC for protecting applications and systems from unexpected power glitches and sudden system crashes. Its small SOT package makes it suitable for many applications and its extended reliability rating makes it suitable for extreme temperature environments. Its wide input voltage range, adjustable reset pulse duration and extremely precise detection give it a competitive advantage over similar ICs in the market. The X40021S14Z-A fits perfectly in the range of power manager ICs (PMIC) - Supervisors.
