Multi-time programmable PMICs optimised for high performance

16-04-2021 | Mouser Electronics | Semiconductors

Mouser is now stocking ACT88329 and ACT88321 multi-time programmable COT PMICs from Qorvo. Both PMICs, from the ActiveCiPS line of products, are optimised for high performance and offer compact form-factor designs.


The PMICs expedite time to market by providing design flexibility for multiple applications, from SSD cards, computer vision (such as security cameras), routers to home control, voice-assisted devices, and low-power mobile uses such as LPDDR5. The same base part can support different end products by changing the PMIC configuration with no special software or firmware. Manufacturers can debug their design and change settings in real-time without altering external components.


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


Each PMIC comprises three DC-DC step-down converters utilising integrated power FETs and two LDOs. All are highly configurable through the I²C interface. The devices are the first integrated PMICs in this configuration to support output voltage as low as 0.5V for low-output applications like LPDDR5.


For development, Mouser also stocks the corresponding ACT88329EVK1-101 and ACT88321EVK1-101 evaluation kits. The boards provide standalone operation, but when connected to a PC by a USB-to-I²C dongle can offer full access to the target PMIC's internal registers and operational capabilities.
