The MIC5164YMM (hereinafter referred to as the ‘IC’) is a special purpose voltage regulator (PMIC) and is designed for active power management in battery and industrial applications. The integrated device combines power supply control, output and key control, which allow for optimal operating efficiency and reliable performance.

The device is a fully integrated active power management IC provides all the necessary regulation, protection and control for a wide range of battery operated applications. It is particularly well suited for portable consumer and wearable electronic markets. In addition, the integrated device combines a wide range of sophisticated logic functions with high-accuracy and low power consumption, which makes it suitable for industrial applications with limited power and space.

The working principle of the MIC5164YMM is as follows. It consists of two stages, a Pulse Width Modulation (PWM) stage and an Output Voltage Sensing (OVS) stage. In the PWM stage, the internal control circuit compares the actual output voltage of the IC with the desired reference voltage or other input signals. If the actual output voltage deviates from the desired, the MOSFETs on the output side are switched, to regulate the voltage level. The Output Voltage Sensing stage is then employed to read the final output voltage of the IC. This sensing output is then compared to the desired reference voltage again, in order to adjust the PWM switching if necessary.

The device features two inputs. The first one is the main input pin, where the battery voltage is connected. The secondary input is optional and is intended to be connected to a reference voltage in order to accurately control the output voltage level. The main input operates as the energy source for the internal circuitry, while the secondary input acts as a reference point for the output voltage control.

The device also features several outputs. First of all, there is a short-circuit protection output, which is activated whenever the output current exceeds the rated limit. This output is designed to activate an external load circuit in order to reduce the total current drawn from the device. The MIC5164YMM also contains a low-side PWM output, which switches the MOSFETs on the output side in order to regulate the output voltage. This output is intended to bridge power supplied from the intermediate node of the MOSFETs, to the output of the IC. Finally, the device contains a logic output. This output can be used to control any external logic control circuit.

Overall, the MIC5164YMM is a highly integrated active power management IC suitable for use in multiple applications. Its ability to regulate the output voltage accurately, provide short-circuit protection and control external logic circuits, make it an attractive device in a wide range of applications, including battery and industrial applications.
