Power management integrated circuit (PMIC) is an important application field for power products in the modern electronics industry. PMIC is usually packed with a wide range of safety and power management features to achieve efficient, reliable, and accurate power management. Supervisors provide overriding control over system power functions and combine monitoring, reset, and other control signals with an embedded system in order to ensure that power is consistently provided and managed properly. The MAX6361HUT46+T is a high-accuracy low-voltage supervisor family with two independent monitoring power-on-reset circuits that reset when any of the two monitored voltage(s) drops below a specified threshold.

The MAX6361HUT46+T configurations offer advantages such as high-accuracy and a low-voltage supervisor (LVS) with highly configurable reset thresholds. This configuration allows the supervisor to be connected to low-voltage power sources without the need for additional components or complex external tracking circuits. The MAX6361HUT46+T can also be used to provide reset of a system due to detection of voltage droops or power transients such as brownouts. In such applications, the MAX6361HUT46+T can be used to monitor multiple supply voltages to make sure that at least one of them stays above a desired reset threshold throughout a transient event.

The MAX6361HUT46+T has two independent monitoring input channels which can be configured for either single or dual-channel operation. In single-channel mode, the supervisor tracks a single input voltage and its active-high reset output goes low when the input drops below its preset threshold. In dual-channel mode, the supervisor tracks two input voltages, and its active-high reset output goes low when either one of the tracked voltages drops below its preset threshold.

The MAX6361HUT46+T has a maximum operating temperature range of -40C to +105C. It operates with either one or two supplies (VCC1 and VCC2). Both supplies may be connected to the same voltage rail, or can be used to reference two independent monitors. The reset active threshold of each monitored voltage can be independently set via external resistor dividers for a desired reset threshold. This provides flexibility in the design of systems such as DSCs, embedded controllers, and microcontroller-based systems, ranging from 1.8V to 5.5V. The reset delay time is adjustable between 1 ms and 35 ms.

The reset output of the MAX6361HUT46+T can be used to drive a power fail output, as well as a reset input of a microcontroller or processor. For load conditions below 1 mA, the reset can be held low as long as necessary. With a higher load current, the reset will return to its high (inactive) state after 2.5 ms minimum. Furthermore, this device offers a wide per-channel supply voltage range from 1.0V to 5.5V.

The MAX6361HUT46+T is an ideal choice for systems with varying supply voltages and a high level of accuracy and configurability. This is because it has the ability to monitor up to two separate supply voltages and maintain a reset output for either one when the set threshold is reached. This enables the device to provide efficient, reliable, and accurate control over system power functions.The combination of high-accuracy, low-voltage monitoring, flexibility of use, and a wide temperature range make the MAX6361HUT46+T an ideal choice for power management applications.
