[{"type":"text","content":"GREENSBORO, N.C., March 07, 2023 (GLOBE NEWSWIRE) -- Qorvo® (Nasdaq: QRVO), a leading global provider of connectivity and power solutions, today announced it has expanded its power management portfolio to include the PAC22140 and PAC25140 Power Application Controller® (PAC) devices. The two PACs are the industry’s first single-chip solutions to offer support for battery packs with up to 20 cells in series (20s). These products leverage an intelligent motor control foundation to enable intelligent battery management solutions (BMS) for a wide range of industrial, e-mobility and battery backup applications. The highly integrated PAC22140 and PAC25140 save designers more than 50% of PCB space and lower total BOM cost by 30%, while reducing time to market leveraging Qorvo's hardware and firmware ecosystem. The devices integrate all essential analog and power management peripherals with a 32-bit Arm® Cortex® M0 or M4F microcontroller and include cell balancing, monitoring and protection for 10s-20s battery packs. The PAC22140 and PAC25140 provide access to multiple analog and digital peripherals required to manage today’s high-cell-count battery packs. These include a programmable-gain differential amplifier, multiple 16-bit Sigma-Delta ADCs for current and voltage sensing, and a 10-bit SAR ADC. A single-supply 145V-buck DC/DC controller generates a 5V system rail to power the device, while an integrated charge pump supports the charge and discharge FET drivers. \"The need for higher cell count solutions is increasing as end users demand longer battery life, faster charging time and lighter overall weight from new battery-powered applications,” said Brian McCarthy, senior manager for Qorvo’s PAC product line. “The highly integrated PAC22140 and PAC25140 provide designers complete solutions for these high-power, high-performance systems.” FeaturePAC22140PAC25140Microcontroller50-MHz Arm Cortex M0 with 10-bit SAR ADC150-MHz Arm Cortex M4F with 12-bit SAR ADCMCU memory32kB - Flash8kB - SRAM128kB - Flash32kB - SRAMCommunication SupportedUART, SPI, I2C/SMBusCAN, UART, SPI, I2C/SMBusGPIOs1724 The PAC22140 and PAC25140 provide a low power hibernate mode of less than 3µA, enabling long storage time with wakeup from push button, timer or charger detection.
