Power management integrated circuits (PMICs) are a key component of any electronic system. Their purpose is to control and distribute power to other components in the system. PMICs are designed to be reliable, efficient and cost effective. Supervisors play an important role in the PMIC landscape by monitoring system health and providing system reset protection. The MAX16114UT+ is a supervisor IC designed for systems requiring low current applications and fault protection.

The MAX16114UT+ is a single-channel, system reset and power supervisor IC with a wide operating voltage range of 2.7V to 5.5V. The device provides active-high push-pull output system reset and open-drain output power-good (PG) signal to indicate that the system\'s power supply is stable. The reset output is asserted when the input voltage falls below the reset threshold voltage. The voltage threshold is adjustable between 1.9V and 4.8V with an accuracy of +/- 5%. The reset timeout period is also selectable from 1ms to 9s. The reset output is deasserted when the input voltage exceeds the reset threshold voltage by the reset hysteresis level. The device works in both active-high and active-low mode and is designed for use with either N-channel MOSFETs or P-channel MOSFETs.

The MAX16114UT+ also has an active-high, open drain power-good (PG) output that is asserted when the voltage on the power-source line is stable within the power good range. The power-good threshold is adjustable between 1.9V and 4.8V with an accuracy of +/- 5%. The power-good rising (PGR) voltage is also selectable from 1ms to 9s.

The MAX16114UT+ is also equipped with a low current push-pull output wake up input. This input can be used to wake up the MAX16114UT+ from sleep mode to enable monitoring of the input voltage and assert the reset output. This feature is useful in systems with low power budgets since it reduces the static current consumption of the device.

The MAX16114UT+ is designed for use in portable applications such as cell phones, PDAs, camera, laptops and digital still cameras where system reset and power monitoring are required. It can also be used in universal serial bus (USB) battery chargers and other consumer electronics applications. The device is available in a tiny SOT23-5 package and is specified over the extended temperature range of -40°C to +85°C.

In summary, the MAX16114UT+ is a single-channel system reset and power supervisor IC with a wide operating voltage range, active-high push-pull output system reset and open-drain output power-good signal. It is designed for use in systems requiring low current applications and fault protection and is suitable for portable and consumer electronics applications.
