Power Management IC (PMICs) are circuit components that are used to supply power to other components within a circuit. PMICs can be found in nearly all electronic devices - from phone chargers to computers and even robotics. The MAX6368PKA26-T is an ultra-low quiescent current (QC) dual-voltage supervisor that provides precise reset, power-on reset, power OK signal, and is used to protect sequencing and reset power supplies during power glitches.

The MAX6368PKA26-T is a dual-voltage supervisor with two independent power supplies, the first being a supply enable (EN) pin and the second being an under-voltage monitoring (UV) pin. This supervisor can monitor two separate supplies, one for each pin, and can be used in applications where high input voltage changes may occur, such as automotive and other industrial applications. The supervisor features low operating current (120uA) to extend battery life in portable applications and nested watchdog timer protection (WDT) to handle communications failures in networking applications.

The MAX6368PKA26-T utilizes independent voltage thresholds to monitor both the EN and UV supply inputs . The EN input monitors an adjustable positive threshold (VTH1) and is used to enable/disable the voltage regulator outputs. The UV input is used to detect under-voltage conditions and monitors an adjustable negative threshold (VTH2). Both thresholds are adjustable by an external resistor network. An active-low reset output (RESET) is provided for each supply. The RESET output signals a power-up reset or supply voltage fault. An active-low power OK output (POK) is signaled when both the EN and UV supplies are within their respective thresholds.

The MAX6368PKA26-T combines two voltage supervisors into one IC, allowing applications to save space and reduce component counts. This supervisor is also optimized for driving MOSFET gates with its low quiescent current, allowing for higher switching frequencies and lower power dissipation. The MAX6368PKA26-T is an ideal solution for automotive, solar, and industrial applications that require robust reset and power good monitoring over a wide temperature range(-40°C to +125°C).

The MAX6368PKA26-T is a Small Outline (SO) package with a lead-free finish, making it RoHS compliant, and meets Automotive Electronics Council (AEC) qualified standards, making it suitable for use in automotive applications. The supervisor is available in four package options including PDIP, SOIC, MSOP, and TSSOP. The MAX6368PKA26-T is available from Maxim in three temperature grades: -40°C to +85°C (K grade), -40°C to +125°C (T grade), and -40°C to +125°C (E grade).

The MAX6368PKA26-T is a versatile dual-voltage supervisor that is suitable for a wide range of applications. This supervisor can be used to monitor two separate voltage supplies, enabling/disabling voltage regulators, activating reset outputs, and signaling power-good conditions. The IC also features low operating current, nested watchdog timer protection, and the ability to drive MOSFET gates, making it an ideal choice for automotive, solar, and industrial applications.
