Qorvo® Introduces Industry’s First Single-Chip Intelligent Battery Management Solutions for 20-Cell Systems
March 07 2023 - 8:00AM
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.”

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.
The PAC22140, in volume production today, is available in a 9x9
mm, 60-pin QFN package, while the PAC25140, sampling today with
production in April 2023, is available in a 10x10 mm, 68-pin QFN
package. Qorvo’s PAC22140EVK1 and PAC25140EVK1 hardware development
kits enable users to develop intelligent BMS solutions by taking
advantage of the fully integrated Arm Cortex-M microcontroller with
a BMS-specific analog front-end (AFE). For pre-production samples
of the PAC25140 and PAC25140EVK1 please contact a Qorvo sales
representative.
