AS1902C23-T

The AS1902C23-T is part of a range of power management ICs (PMICs) known as supervisors. This range of products provides integrated circuit solutions for monitoring, resetting and keeping applications safe from potential damage or failure. The AS1902C23-T supervisor is a versatile, highly integrated device with features that make it ideal for a variety of applications, from protecting high performance microprocessors and ASICs to keeping consumer electronics from failing.

At its core, the AS1902C23-T supervisor provides a power-safe reset and monitoring system by monitoring the voltage of the primary voltage rail and providing a reset signal when the voltage goes below a preset threshold. The supervisor is also capable of monitoring secondary voltage rails and generating an output signal to alert the system when the voltage is out of range. This output signal can then be used to inform the system to take appropriate action to rectify the voltage issue.

The device is a single-chip solution, with integrated non-volatile memory (NVM) to store a range of system settings such as reset thresholds and power-up timeout values. It has a wide range of input and output pins allowing it to be connected to a variety of system interfaces. The device also has two leaded Standard Small Outline-N (SSON) packages for easy mounting on PCBs as well as a space-efficient package for applications with limited board space.

The main feature of the AS1902C23-T supervisor is the integrated Power-On Reset module (POR), which is used to generate a reset signal when the voltage of the primary voltage rail falls below a predetermined threshold or during a system power-up. This reset signal is then used to initiate a system reset so that the system can recover from any potential faults or system instability. In addition to the POR module, the supervisor also has on-board logic to detect abnormal conditions such as overvoltage and supply surges. This logic can then be used to take corrective action such as powering down the system or disabling the power rail.

In addition to providing a reset and monitoring system, the AS1902C23-T supervisor also offers a range of programmable features to aid in the protection of system components and devices. These features include programmable undervoltage detection (UV) and overvoltage detection (OV) thresholds, programmable power-up timeout value, built-in thermal overload protection, and programmable logic levels for reset, monitoring and power supply rails. All of these features are designed to keep system components safe from potential damage or failure, while maximizing the performance and energy efficiency of the system.

Overall, the AS1902C23-T supervisor provides a complete and reliable solution for providing a reset and monitoring system. The integrated features, such as the POR module and various configurable settings, make it an ideal choice for a variety of applications that require reliable, power-safe reset and monitoring.
