MAX6865UK16D5L+T is a family of PMIC - Supervisors, which are used to provide reset functionalities with features like overvoltage, undervoltage and over temperature protections. It is a 3-Game Piece, highly integrated supervisor with a high current reset driver, temperature warning and a voltage supervisor for local power supplies.

The MAX6865UK16D5L+T supervisor is designed for use in industrial instrumentation, automotive, consumer and telecommunications systems. It is integrated with a low-power CMOS process and offers power-on reset, active low reset, onboard voltage supervisor, thermal warning or shutdown, choice of reset outputs and adjustable reset threshold voltage range. It also provides a reset debounce of up to 256ms for most reset conditions.

MAX6865UK16D5L+T provides a wide operating voltage range of 0.8V to 5.5V to support various power supplies. The integrated supervisor monitors five power supply voltages, four local power supplies and one system power supply, and supports four active-low reset outputs. The reset outputs will assert when any monitored voltage is lower than the selectable reset threshold. It keeps track of the maximum NAND count and has the ability to push an output signal to the MAX6865UK16D5L+T using a combination of timer, voltage, temperature and count inputs.

Its operating temperature range is 0°C to +85°C, making it suitable for use in industrial environments. The operating current ranges from 0.010mA to 0.025mA at 0.8V to 3.0V, and from 0.0030mA to 0.0070mA at 3.3V to 5.5V. The reset timeout period is adjustable from 15ms to 256ms and the reset hold time is 30ms.

The MAX6865UK16D5L+T has versatile slew rate options for improved noise immunity, and provides a variety of ways to connect and interface. It supports I2C and SPI bus protocols as well as standard TTL-level interfaces. It also features ultra low power consumption, optimized power consumption in shutdown mode and an integrated power-on reset circuit.

The working principle of MAX6865UK16D5L+T is to monitor the power supply voltages, and when any voltage is below the set threshold, it will output an active low reset signal. It also monitors the maximum count, temperature and reset timeout, and pulls the reset pin down to ensure that the system comes up without any lockup or power transient problems.

In addition, it has user programmable reset delay time, reset hold time and reset threshold voltage. The user can easily program these settings based on the system application needs. The reset threshold voltage is adjustable between 0.8V to 5.5V, with setting values that can be programmed via the I2C or SPI bus.

MAX6865UK16D5L+T is an advanced supervisor with a variety of integrated features, offering system designers with a reliable, cost efficient and easy-to-implement solution for all reset applications. It is highly reliable, has low power requirements and provides multiple communication interface options.
