PMIC - Supervisors

The MAX6320PUK33BX+T is a monolithic, low-power voltage supervisor designed for use in high performance, low power, portable applications. It operates from a single 2.7V to 3.6V supply, and draws a very low 20uA current. The MAX6320PUK33BX+T provides a number of features essential for easy-to-use and reliable application management, including: complementary active-low, open-drain reset outputs, an adjustable reset-assertion threshold from 0.53V to 9.3V, low supply current, numerous reset-assertion and release timing options, thermal reset protection, and open-drain reset signals with a 200ms reset-release time.

Applications

The MAX6320PUK33BX+ has been developed to meet the demands of high performance, low power, and portable device applications such as: SmartPhones and PDAs, Wireless Peripherals, Digital Cameras, and Portable/Consumer Electronics. It offers a wide reset-assertion range and numerous reset-assertion and release timing options, making it ideal for relaying standby and power shutdown sequences. Its open-drain reset outputs, supply voltage tracking, and robust reset-assertion and release timing scheme allows for the propagation of power management reset signals throughout multiple devices in a system.

Working Principle

The MAX6320PUK33BX+ is designed to offer reliable and accurate monitoring of input supply voltages as well as reset-assertion and release timing options. Labels within its die outline the input supply voltage and reset-assertion and release timing. The MAX6320PUK33BX+ is designed to continuously monitor the input supply voltage and will assert a reset signal when the supply voltage falls below the preset level. The reset signal will be deasserted either after the preset reset-release time has elapsed or when the supply voltage rises above the preset level.

The MAX6320PUK33BX+ also offers a power shut-down sequence. This sequence is initiated by the assertion of the power shut-down signal (PSD) input, which in turn will cause the reset signal to become active and the reset-assertion timer to begin counting. When the power shut-down signal is released, the reset-release timer will start counting and the reset signal will be deasserted after the preset amount of time has elapsed. The power shut-down sequence offers noise immunity by requiring a signal-level change on the PSD input in order to begin the reset-assertion and release cycle.

The MAX6320PUK33BX+ also offers an adjustable reset-assertion threshold that can be adjusted between 0.53V and 9.3V in order to suit the application requirements. This allows for the reset threshold to be customized to ensure that the reset signal is accurately and reliably monitored.

Conclusion

The MAX6320PUK33BX+ is an ideal solution for portable applications, providing features such as high performance and low power operation, wide reset-assertion range and adjustable reset-assertion threshold, robust reset-assertion and release timing, thermal reset protection and open-drain reset signals with a 200ms reset-release time. Additionally, its power shut-down sequence offers noise immunity and ensures that reset signals are accurately and reliably made throughout multiple devices in a system.
