MAX6310UK34D2-T

The MAX6310UK34D2-T belongs to the family of PMICs, more specifically to the Supervisors family. This PMIC is a low-cost, single-channel, fixed-threshold, watch-dog supervisor that is designed to protect microprocessors by resetting them when their operations become non-deterministic. The MAX6310UK34D2-T is a voltage-driven (VIO) device that can operate on various supply voltages and down to as low as 0.8V compared to 1.8V for other supervisory ICs. This makes it a good fit for battery-supplied applications.

The MAX6310UK34D2-T can supervise both system and processor supplies, providing an accurate detection of supply drops below the reset voltage as well as important brown-out reset functions that resets the system if the supply is dropped below a certain voltage. The MAX6310UK34D2-T also monitors one or two external watchdog signals from a controlling microprocessor or microcontroller, providing pulse-width-dependent reset. To avoid bugs in the processor code from allowing unintentional microprocessor or microcontroller reset or system reboots, the MAX6310UK34D2-T has an effective programmable timer switch that will reset the device if the time between successive watchdog pulses exceeds the predetermined time threshold.

The MAX6310UK34D2-T is suitable for a wide range of applications that include systems powered by batteries, such as PDAs, smart phones, and handheld industrial instruments. Its low current consumption makes it suitable for power-supplied applications in which the power must be supplied to the reset circuit continuously, such as in large and complex computer systems. The MAX6310UK34D2-T provides the highest level of accuracy while protecting against brown-out reset and restoring the system to its normal operational state.

For the most demanding applications, the MAX6310UK34D2-T provides an optional watchdog timeout feature that guarantees power-on reset if the watchdog signal is not received within the programmed timeout period. This ensures the system cannot become trapped in an unpredictable state. In this case, the MAX6310UK34D2-T can be used as an independent reset source, without the need for additional control logic. Additionally, the MAX6310UK34D2-T has an optional output delay feature that allows the reset signal to remain asserted for as long as 1.2 seconds before it is released. This is important for applications that require long system reset recovery times.

The MAX6310UK34D2-T is an effective supervisor for single-supply and dual-supply systems. It provides flexible reset reset holdoff and system reset functions with minimal component count, which makes it ideal for low-power system designs. As a result, the MAX6310UK34D2-T is ideal for applications that require power-on reset, watchdog monitoring, brown-out reset, and system reset functions in a low cost, low power package.
