Power management integrated circuit (PMIC) plays an important role in providing good performance of electronic devices, particularly for portable electronic devices. The ADM13307-25ARZ-RL7 is one of the PMIC products from Analog Devices, which is a high-performance and low-cost power supervisor for handheld electronic equipment and portable systems. The device integrates all of the supervisory functions required to maintain microprocessor-based systems and to eliminate the need for additional discrete components.

The ADM13307-25ARZ-RL7 is classified as a PMIC supervisor, which serves to monitor the power input, system power supply, microprocessor and I/O devices. It is designed to monitor microprocessors and system voltages, and is capable of signaling presetting warning or reset thresholds. The ADM13307-25ARZ-RL7 provides multiple power input monitoring signals, adjustable undervoltage lockout and adjustable digital reset signal, RF signal-off detection and high-side MOSFET control signal. Due to its flexibility and small size, it is a commonly-used device for a wide range of applications, such as portable electronic equipment and personal digital assistants (PDA).

The working principle of the ADM13307-25ARZ-RL7 is rather straightforward. The device detects system voltages on an ongoing basis, and then compares them to internally generated voltage thresholds. In the event of a detected overvoltage, undervoltage, current leakage, or other abnormal power condition, the supervisor can drive start-up delay logic as it waits for the condition to stabilize and return to normalcy. It then outputs a reset signal to restart the system.

The ADM13307-25ARZ-RL7 is designed to provide monitoring of multiple power supplies and reset logic family microprocessors. Its features include wide operating voltage range of 1.80V~3.6V, 2.5V output power supply, five control signals, adjustable delay timer, push button reset control and unique clear reset command. The device covers a wide range of input voltage range from 1.3V to 5.5V and is capable of withstanding ±20V transient pulses. It is a cost-effective device for various projects, offering superior performance and reliability.

In conclusion, the Analog Devices ADM13307-25ARZ-RL7 is classified as a PMIC supervisor device which provides multiple power input monitoring signals, adjustable undervoltage lockout and adjustable digital reset signal. Its features include a wide operating voltage range of 1.80V~3.6V, five control signals, adjustable delay timer and push button reset control. The device has proven to be reliable, cost-effective and widely-used for multiple applications such as portable electronic equipment and PDA.
