Power Management ICs, or PMICs, are integrated circuits that monitor, control and manage the power level of a wide range of electronic devices.

The MC33164D-3R2G is a high-performance, space-saving 4-channel PMIC specifically designed for battery-powered portable electronic devices. This PMIC is part of a family of space-saving PMICs that provide the highest power savings when the device is in low power sleep mode and the best performance at lower power levels during active operation. It also provides an easy-to-use, self-programming, low-power and fault-protected power management unit.

The MC33164D-3R2G is part of the PMIC-Supervisors product family, which includes a range of PMICs with integrated voltage monitoring and supervisor functionality. Supervisors are used within power management and supervisor circuits to ensure that the power supply remains stable and the device does not operate outside of its recommended operating voltages. This ensures the reliable operation of PMICs and the system-level products.

The MC33164D-3R2G provides high-frequency switching, power path management and 5-channel active power management, making it the ideal choice for applications that require the best of both worlds – high performance and low-power sleep mode. It offers excellent performance at current levels up to 2A, accurate and fast transient response, active power management and adjustable switching frequency up to 10MHz. The device also features low standby current, shrinking external component size, support for fast charging and low-impedance Power MOSFETs for improved efficiency.

The MC33164D-3R2G is suitable for a wide range of applications, including consumer electronics, automotive, healthcare, industrial and consumer applications, as well as in products with limited board space such as consumer-grade 3D printers.

In terms of its working principle, the MC33164D-3R2G can be considered as an integrated system in which various functions are combined together to provide a complete set of power management tools. The various functions can be divided into two main categories: active power management and voltage monitoring/supervision.

At the heart of this PMIC is the active power management module, which is responsible for converting inputs from the battery into regulated output voltages. The module handles power routing and voltage scaling under various operating conditions and converts the input voltage into required output voltages, optimized for maximum power savings. The module is capable of providing up to 5 channels of active power management, adjustable switching frequency and fast transient response.

The MC33164D-3R2G also integrates a supervisor circuit that monitors battery voltage, temperature and other system parameters to ensure a safe operation of the device. It features adjustable trip levels, auto-reset, under voltage lockout and a variety of other monitoring features.

Overall, the MC33164D-3R2G is an excellent choice for applications that require high performance and low-power sleep modes. Its space-saving design allows for a shrinkage of the external component size and improved efficiency, while its integrated active power management and supervisor circuits make it an ideal choice for power constrained portable electronic devices.
