Introduction

The MAX6381XR31D2-T is an advanced power management integrated circuit (PMIC) designed for battery-powered, point-of-load applications. It\'s a members of Supervisors family from Maxim Integrated and combines several power management functions onto a single chip. It includes a voltage supervisor, voltage regulator and a buck-boost charge pump and provide an ON/OFF control of an external PMOS power switch.

Application Fields and Working Principle

The MAX6381XR31D2-T is designed for portable and mobile applications, such as medical instruments, consumer electronics, and industrial electronics. This PMIC offers efficient power delivery and precise voltage regulation, as well as low on-resistance, high-side switches to connect and disconnect power without involving the system\'s supply voltage.

The MAX6381XR31D2-T is a unique PMIC has a voltage supervisor function, a voltage regulator, a buck-boost charge pump, and an on/off power switch for external P-MOSFET. The voltage supervisor provides supply sequencing and sequencing reset signal to the power sequencing system and monitors the voltage level of the VDD line. The voltage regulator ensures an accurate output voltage from the VDD line. The buck-boost charge pump can be used to convert the voltage between input and output on the VDD line and can deliver up to 1.5A of current across its internal MOSFETs. The on/off power switch can be used to switch on/off the power to the external devices. The integrated logic block controls all the functions of the P-MOSFET\'s power switch and the charge pump, which can be operated independently or in conjunction with each other.

The voltage supervisor function of MAX6381XR31D2-T supports up to two voltage levels and two reset signals. The voltage supervisor output line provides two power supply reset signals (V1 and V2) that can be used to sequence the power-up sequence of the external devices. The voltage supervisor also provides an auxiliary output for monitoring the VDD line voltage level. The voltage regulator supports adjustable output voltage range between 0.6V and 5V. The buck-boost charge pump supports input voltage from 1.8V to 5V and provides up to 1.5A current. The power switch controls the power to the external power switch by providing a control signal to the P-MOSFET.

Conclusion

The MAX6381XR31D2-T is a PMIC for portable and mobile systems. It combines a voltage supervisor, voltage regulator, and a buck-boost charge pump into a single solution, enabling efficient power delivery and precise voltage regulation. The power switch to the external P-MOSFET can be used to provide ON/OFF control without involving the system\'s supply voltage. In conclusion, the MAX6381XR31D2-T provides an ideal solution for point-of-load applications in portable and mobile systems.
