Introduction
Qorvo's PAC25140EVK development platform is a complete hardware solution enabling users not only to evaluate the PAC25140
device, but also develop battery management solution revolving around this powerful and versatile ARM
microcontroller. The module contains a PAC25140 Power Application Controller
energize the MCU and its internal peripherals once power is applied.
To aid in the application development the PAC25140EVK offers access to every one of the PAC25140 device's signals by means of a
series of male header connectors.
The PAC25140EVK also contains access to an external USB to UART module enabling users to connect the evaluation module to a
PC computer through a conventional Virtual Comm Port which can then be used in the communication efforts by taking advantage of
the PAC25140's UART interface. Graphical User Interface (GUI) software suites can be employed to externally control application's
features.
Finally, the PAC25140EVK module gives access to the PAC25140's SWD port allowing users to both program the application into the
device's FLASH memory, as well as debugging the application in real time. The provided 4 pin connector is compatible with a decent
variety of SWD based debugger/programmer modules, widely available. See PAC25140 BMS Getting Started Guide for additional
information.

145V (Abs Max). The PAC25140EVK is optimized to operate with voltages ranging from 19V to 90V Nominal (100V Abs Max FETs). When the VIN input voltage goes above 19V, the system exits UVLO protection and all subsystems, including voltage regulators, analog front end and microcontroller, are enabled. - Page 6 Connector P7 offers access to the PAC25140 resources on PORTF utilized for temperature sensor using MCU’s ADC inputs. Each temperature sensor input includes TS and GND (System ground). However, the PAC25140EVK uses three 10k resistor instead of NTC resistors as default. In order to use NTC for temperature sensor, remove R43, R44, R45 resistors and connect NTC resistors at P7 port.

- Page 8 The Qorvo PAC25140 is a Smart Battery Monitoring System that can monitor a 10-series to 20 series battery pack. In the actual application, the number of used cells may be less than 20 cells. PAC25140EVK cell count can be configured by using the selection resistor which connects the corresponding top cell to the BAT+ connector.
- Page 9 PAC25140EVK Setup for Evaluating with Load current The setup for the PAC25140EVK evaluation module with load current requires the following connections: Install cell simulator shunts on J7, J8 headers. Please follow the Cell Count Selection section to configure battery pack accordingly.

- Page 11 PAC25140EVK Setup for Evaluating Charge and Discharge Currents To evaluate the Charge and Discharge, PAC25140EVK can be setup by using bipolar power supplies which feature current sink and source capabilities. If the bipolar supplies are available, they can be used for both BAT and PACK side without re-connecting the equipment.
- Page 12 The top and bottom of the cell stack are connected to BAT+ and BAT- spade tab connector, cells voltage are connected by corresponding screw terminal connectors. Although the PAC25140EVK has designed with low side drive protection fuse, the short link components are installed to allow easy evaluation without the concern of activating the Fuse Blow.
