MAX6366LKA26+T

Integrated circuit (IC) supervisor circuits, also known as "pure regulators," are power management ICs (PMIC) used to monitor the core voltages of microprocessors (μPs) and other critical voltage railings in complex power system design, such as those found in mobile, portable and other handheld/ wearable devices. Receiving input from numerous subsystems and outputting commands to power management modules, PMICs have become an indispensable part of any device\'s control system. The MAX6366LKA26+T is an example of a PMIC supervisor featuring remote sensing architecture, offering stabilized and reliable ground-referenced system monitoring.

The MAX6366LKA26+T PMIC supervisor includes a remote sensing input (REF), two adjustable reset outputs (RESET/nRESET), an active-high power-on reset output (POR), and an active-high low-voltage warning (LW) output. Additionally, it includes a three-state active-high power-fail (PFO) output, allowing the device to support both a 3.3V and a 1.8V power rail system.

The MAX6366LKA26+T PMIC supervisor operates across a wide range of supply voltages (2.7V to 5.5V), and its wide input voltage range allows for optimal system configuration flexibility. In addition to monitoring the microprocessor\'s core voltage, the device also provides remote sensing to achieve improved accuracy of the µP core supply rail. The reset outputs (RESET/nRESET) are adjustable from 2.5V to 5.5V in 100mV increments. The MAX6366LKA26+T also includes a three-state active-high power fail (PFO) output, allowing the device to support both a 3.3V and a 1.8V power rail system.

The active-high output for each of the PMIC\'s outputs is designed to quickly open the gate of a P-channel power MOSFET in the event of a voltage anomaly. In the RESET/nRESET output, the open-drain active-high PWROK signal indicates that the microprocessor\'s main power (VCC) is in the range determined by voltage supervisor settings. An active-high output with pre-defined pull-up resistor is available as well on PWROK. The MAX6366LKA26+T PMIC supervisor also features an LW output with a typical accuracy of 200mV, indicating when the system voltage drops below the designated LT voltage set by the voltage supervisor.

The MAX6366LKA26+T PMIC supervisor can be used in a variety of applications. It is ideal for power system design in cost-sensitive mobile and portable applications, such as mobile phones, PDAs, digital cameras and camcorders, as well as industrial and automotive applications. It can also be used to create custom power management designs in gate drivers for motor controllers, logic power supplies, hot-swappable power supplies, DSP and microcontrollers, etc.

To summarize, the MAX6366LKA26+T PMIC supervisor is a versatile device with remote sensing architecture that provides a stabilized and reliable ground-referenced system monitoring for mobile, portable and other handheld/ wearable devices. It has an adjustable reset output (RESET/nRESET) and an active-high, low-voltage warning (LW) output. The device also offers support for both a 3.3V and a 1.8V power rail system. This device can be used in a wide range of applications, such as mobile phones, PDAs, digital cameras and camcorders, as well as industrial and automotive applications.
