Power Management Integrated Circuits (PMICs) are highly complex circuits that help to manage and direct the power used in modern computing and mobile technologies. They are responsible for controlling voltage, current and temperature levels so that regulated power is provided to components and devices without hardware or software solutions. PMIC - Thermal Management is one of the main areas which a PMIC needs to address.The MAX6639ATE+ is an example of a PMIC designed for thermal management. It is a single-chip solution tailored for applications where a separate, dedicated thermal control system is needed. The MAX6639ATE+ offers a complete thermal management solution that combines sophisticated temperature sensing, intelligent fan control and reliable thermal protection functions all on one chip.The MAX6639ATE+ offers a wide range of features and benefits to the system designer. It includes:

• intelligent automatic fan speed control according to temperature thresholds for optimum cooling efficiency
• precise temperature sensing in a variety of industry standard packages (SOT23, DFN and TSSOP)
• comprehensive features including adaptive deadband/hysteresis, temperature offset and temperature sense resistors ordering
• software temperature compensation to ensure fan speed is accurately adjusted to account for temperature drift
• hardware fault detection that automatically reduce fan speed when the fan fails or cannot reach the set point
• auto-restart and one-shot modes to prevent system runaway due to fan failure
• thermal protection with programmable temperature trip points
• fully integrated fan driver and temperature sensor that minimize BOM count
• low power shutdown when excessive temperature has been detected

The MAX6639ATE+ works by sensing the temperature of the surrounding environment and controlling the fan and its speed accordingly. It uses an internal voltage reference to provide accurate temperature measurements and uses a programmable temperature trip point to control fan speed. This trip point can be set to the desired temperature in order to control the cooling of the system efficiently without the need for external control. The MAX6639ATE+ also includes a programmable hysteresis that defines the temperature band width so that the fan will be ramped up at a defined temperature and ramped down once the temperature drops below a specified value.The fan speed is also controlled by the MAX6639ATE+. The fan speed can be controlled either by PWM or through a potentiometer. The MAX6639ATE+ features a 4-bit pulse-width modulated (PWM) fan driver that can be used to precisely control fan speed and offer the maximum cooling efficiency with minimal fan noise. It also features a potentiometer input that allows the user to manually adjust fan speed according to temperature. The MAX6639ATE+ also includes precise fan speed monitoring that monitors fan health and automatically reduces fan speed when a fan fails or cannot reach the set point.The MAX6639ATE+ also includes hardware fault detection that protects against system runaway due to fan failure. It also includes a thermal protection feature that allows the user to program their own temperature trip points. This feature shuts down the fan entirely when the temperature exceeds a programmed limit, thus protecting the system from excessive heat. In summary, the MAX6639ATE+ is a highly advanced PMIC designed for thermal management applications. It provides highly accurate temperature sensing, intelligent fan control and reliable thermal protection in a single chip. It allows for precise thermal control with auto-restart and one-shot modes to prevent system runaway due to fan failure. Its comprehensive features provide the user with maximum control and flexibility in how their system is cooled and also protects against excessive heat.
