Power Management IC (PMIC) is an essential electronic component for today’s advanced electronics products. PMICs, also known as Supervisors, integrate a variety of voltage and current sensing and control functions, as well as other features, into a single integrated circuit, thus allowing manufacturers to reduce the size and cost of their designs while maintaining improved system reliability. One popular example of such a device is the XC6118C28CGR-G.

The XC6118C28CGR-G is a highly integrated Power Management IC (PMIC) developed specifically for small form factor applications. It integrates four high-efficiency, ultra-low dropout linear regulators (LDOs) with up to 900mA peak current drive capability, one high precision-voltage comparator, a master reset signal generator, and 8-bit configurable digital I/O. This single IC provides manufacturers with an extremely power-efficient, space-saving regulator solution for low-end board designs.

The XC6118C28CGR-G is designed for applications requiring high performance, low power consumption, and simple and flexible power supplies. Its target applications include battery operated electronic devices such as portable medical instruments, automotive applications, and industrial hand-held equipment. The device has been designed for applications requiring low quiescent current, high power efficiency, and small size. Thanks to its tight tolerance, low-noise, and tight loop behavior, the XC6118C28CGR-G is also suitable for a variety of low-power analog and mixed-signal applications.

The XC6118C28CGR-G is a Quiescent Current Controlled (QCC) PMIC supervisor, which means that it automatically adjusts its output voltage according to its input voltage. When power is applied to the device, an internal voltage regulator generates a reference voltage that is used as the basis for controlling the four linear regulators. Voltage regulation is then maintained by monitoring the input voltage and adjusting the output in order to stabilize the output voltage. This is achieved by measuring the input voltage and then adjusting the output voltage to maintain a constant output voltage regulation over the supply range. This feature helps reduce power consumption, improves efficiency, and extends battery life.

The XC6118C28CGR-G also features a sophisticated open-loop current-limiting feature, as well as a host of power supply/battery management features such as pre-bias fault protection, over-temperature protection, and under-voltage lockout. The device is designed to be tolerant to negative transients and transient overloads and is capable of cyclic overload protection up to 3.6A. It also features a built-in sequencer to enable orderly turn-ON and turn-OFF of its regulators.

The XC6118C28CGR-G is a versatile PMIC supervisor suitable for a wide range of applications. It offers excellent power efficiency, high integration, and complex fault protection functions, making it an ideal choice for small form factor designs that require high performance and low power consumption.
