Power loss protection PMICs

Qorvo® Launches Two High-Performance PMICs for Data Center, Cloud Storage and Computing Applications.

20200212 ACT85610 86600small

The Qorvo ACT85610 PMIC is the only product on the market with a monolithic, compact design that combines high-performance power loss protection (PLP) and programmable power management in a single chip.

All eFuse, buck regulators and boost regulator FETs of the ACT85610 are integrated. It covers the common 3.3V, 5V and 12V power inputs for enterprise solid-state drive (SSD) applications and provides seven programmable general-purpose input/outputs (GPIOs) for status reporting, sequencing control, system auto discharge and interrupts. The integrated 8-channel, 12-bit analog-to-digital converter (ADC) enables critical system parameter measurements and monitoring. The ACT85610 PMIC also implements autonomous storage capacitor health checking and accurate capacitance reading, which enhances system monitoring and lifetime estimation.

The Qorvo ACT86600 PMIC integrates high-current and high-efficiency regulators. This highly configurable and compact device has five step-down regulators, a buck-boost regulator and seven programmable GPIOs. Each regulator has multiple frequency settings for maximum flexibility. High-current regulators can be optionally configured as a single two-phase regulator with twice the current, to support up to 12A of DC current. GPIOs can be used to sequence external regulators, control signals to turn regulators on/off, control voltage, provides a power good status, monitor system voltage and many other functions.

 David Briggs, senior director of Qorvo's Programmable Power Management business, said, "These products reflect Qorvo's ongoing commitment to delivering performance and flexibility options for system designers. In particular, the single-chip combination of PLP with power management creates a game-changing device that maximizes efficiency and reliability, and provides the highest levels of integration, configurability and flexibility in enterprise applications."

The ACT85610 and ACT86600 are available now and offer these specifications:
