Qorvo ActiveCiPS ACT88329 and ACT88321 PMICs

Qorvo has released the ACT88329 and ACT88321 multi-time programmable constant-on-time (COT) power management ICs (PMICs). Both PMICs, from the ActiveCiPS line of products, are optimised for high performance and compact form-factor designs.

The PMICs are said to accelerate time to market by delivering design flexibility for multiple applications, from SSD cards, computer vision (such as security cameras) and routers to home control, voice-assisted devices and low-power mobile uses such as LPDDR5. The same base part can be used to support different end products simply by changing the PMIC configuration without special software or firmware. Manufacturers can debug their design and change settings in real time without changing external components.

The PMICs integrate five voltage rails, a sequencer and seven configurable general-purpose IOs (GPIOs) in a small 2.18 x 2.58 mm 30-ball WLCSP package. The GPIOs support two-level input voltage monitoring and can be configured for different features and purposes like interrupt, reset, external enable and sleep/deep sleep modes. The ACOT control mode provides high performance at low output voltage.

Each PMIC includes three DC/DC step down converters using integrated power FETs and two low-dropout regulators (LDOs). All are highly configurable via the I²C interface. They support output voltage as low as 0.5 V for low-output applications like LPDDR5.
