The MAX6385XS43D2-T is a micro-power supervisor with a maximum operating current of 0.1μA. It is a supervisor IC (Integrated Circuit) used in Field Programmable Gate Array (FPGA) applications or other embedded systems. The device offers a versatility in its capabilities and its use cases have been found in many designs, such as FPGAs, micro controllers (MCUs), system control, and other embedded systems. The MAX6385XS43D2-T is designed to provide accurate monitoring, resetting, and protection of microelectronic devices with exceptional power management capability. It acts as a micro-power supervisory circuit, providing power resetting, under-voltage and over-voltage protection, power up sequencing, and power sequencing control.

The MAX6385XS43D2-T features a resettable watchdog timer, power-on reset (POR), a power-down reset (PWDN) for turn-off control, and a switchable passive power-on reset (PPOR). The device has an operating voltage of 2.3V to 5.5V, a 0.1uA operating current and requires a 0.45µA standby current. It also has an adjustable watchdog timer from 10 milliseconds to 1 second. The POR and PWDN are selectable between active low or active high, and the PPOR is programmable for active low or active high reset. When the power drops below or rises above the preset thresholds, the device will detect the power failure and generate a reset signal. The device features a high-accuracy adjustable POR and under-voltage protection (UV). The POR and UV thresholds are programmable with a 3-bit DAC. Its low-power operating current allows the device to detect and reset devices with low power consumption.

The MAX6385XS43D2-T can be used to protect devices from over-voltage and under-voltage faults and provide a flexible sequencing of power rails during system startup and shutdown. It can be used in a variety of microelectronic systems to monitor and reset power, such as FPGAs, MCUs, system control, and other embedded systems. The device is able to reset the microcontroller in the event of a power failure or over-voltage fault, and it can sequence the power rails to ensure proper power-up and system shut-down. The power sequencing control can be used to reset and enable system components in a pre-determined order or cascade multiple power rails for system restart and shut-down.

The device also offers the added advantages of a compact package size, a low-cost design, and a wide selection of dynamic and static operating modes. The device is available in a 5-pin SOT-23 package and a 6-pin SOT-25 package. Additionally, it is available with an internal voltage reference or an external reference. The MAX6385XS43D2-T is a highly versatile, cost-effective power supervisor, providing power resetting, under-voltage and over-voltage protection, power-up sequencing, and power sequencing control.
