The MAX16004CTP+ is a 3-channel supervisor that combines precision monitoring of voltage and supply current for Power Management IC (PMIC) applications with battery-type-detection circuitry. This supervisor is versatile enough to monitor and protect a wide range of end products, including laptops, TV\'s, digital cameras, consumer electronics, routers, and telecom appliances. It is suitable for Li-ion and Li-polymer battery charger systems.

The MAX16004CTP+has two voltage comparators and one current comparator designed to monitor output voltages and supply currents. The voltage comparators are designed to detect overvoltage and undervoltage conditions. The current comparator is designed to detect any overcurrent condition. It also has two general-purpose inputs that can be configured as digital inputs or used to monitor system events.

The battery-type-detection circuitry is used to detect whether the battery being used is of Li-ion or Li-polymer type. The battery-type-detection circuitry offers a much higher accuracy than voltage detection by quickly detecting the battery type and then providing the appropriate settings for charging.

To ensure very fast and accurate detection of an overvoltage, undervoltage, or overcurrent condition, the MAX16004CTP+ uses an analog-to-digital (A/D) converter to monitor the comparator\'s output once it is set to a particular threshold. To increase accuracy and response time, both the voltage- and current-sensing units have a programmable multiplication factor.

The MAX16004CTP+ also features various features that make it easy to use and configure. These include a 2-wire serial port, an interface port, and a reset input that can be used to reset the device whenever a fault condition occurs. It also has an integrated voltage regulator, a programmable open-drain output, and an integrated watchdog timer that helps prevent false triggering.

The MAX16004CTP+ is designed to provide greater reliability and reduce system design time. It also offers very low power consumption and low EMI, making it an ideal solution for PMIC applications. With its high accuracy and fast response, the MAX16004CTP+ helps protect end systems from damages due to voltage and current over/under-voltage.
