The MIC6315-46D4U TR is an industry-leading power management IC (PMIC) used mainly in the field of supervisors. It is designed to provide high-accuracy voltage monitoring and reset functions, over-voltage and under-voltage warning functions, and timer-based reset functions, with the purpose of maintaining proper operation of the power systems.

The MIC6315-46D4U TR is composed of a voltage Supervisor and four reset circuits, each of which have been pre-programmed with adjustable characteristics. The Supervisor comprises of two independent voltage monitoring circuits and two independent comparators. The two voltage monitoring circuits allow the system to monitor a wide range of voltages up to 28V and 18V respectively. The two comparators can monitor two voltages at different levels, each with an accuracy of 0.5% over the entire supply voltage range.

The four reset outputs can be used to control various power domains. The Reset Outputs are designed to lock in either the active low or active high state at power-up of the ICs, depending on the situation. A Reset Output is available for each monitoring voltage, with each of them having its own independent active time and inactive time settings.

The MIC6315-46D4U TR also provides a watchdog timer function which can be used to protect against a runaway processor or false system diagnostics condition. The watchdog timer circuit has a maximum timeout period of 15 seconds, allowing for a wide range of applications.

Moreover, the MIC6315-46D4U TR offers an adjustable delay timers, allowing for precise timing of events. This can be used to delay the powering-up of the power domains or for precise calibrations.

The reset circuits in the MIC6315-46D4U TR are designed to be tolerant to most adverse conditions. The reset circuits are capable of withstanding a wide temperature range (–40°C to 125°C) and operating at a low supply voltage (2.0V typical). The MIC6315-46D4U TR can also handle up to 65mA of reset current and supports a maximum voltage spike of 20V.

The MIC6315-46D4U TR is further protected against ESD, spikes, and high-frequency transients, meaning that it can work in even the harshest environments with no disruption.

Overall, the MIC6315-46D4U TR is an ideal choice for supervisors. Its combination of low power consumption, accuracy, and robust design makes it an invaluable asset in any power system.
