Qorvo at embedded world 2023

At embedded world 2023, Qorvo is showcasing the latest in its power management portfolio: 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 analogue 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 analogue 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 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. The integrated high-voltage buck reduces thermal issues by supporting the system with a 5V regulated supply up to 225mA. An integrated 3.3V-LDO supplies up to 90mA for running additional peripherals. An analog MUX is connected to the SAR ADC for safety checks on internal nodes.
