ACT8847EV ® Rev 2, 08-Oct-11 ACT8847 Evaluation Kit FEATURES GENERAL DESCRIPTION • Fully Assembled and Tested PCB • Allows Simple Evaluation of the ACT8847 • Probe Points for Easy Measurement The ACT8847EV contains a fully assembled and tested circuit board designed to demonstrate all the features of the ACT8847. The ACT8847EV includes a variety of test points and jumpers as necessary to configure and evaluate the ACT8847’s functionality. System start up/verify REGx operation on EV Board QUICK START GUIDE Recommended Equipment The following procedure must be followed to evaluate the IC operation. 1) Variable Power Supply 2) DMM and Oscilloscope 1) Pressed push-button S2 (nPBIN) to enable system (turn IC on). Connect J11_1 pin (PWRHLD) and J11_2 pin (PWREN) to J12 (V_I/O) to hold system operation before nPBIN released. 3) ActivePMUTM Dongle and Cable 4) Load Resistors or Electronic Load Quick Start Operating Procedure 2) Released push-button when PWRHLD pin and PWREN pin has already connected to V_I/O. The following procedure should be used when operating the ACT8847EV for the first time to verify correct operation. 3) Verify REGx (REG1, REG2, REG3, REG4, REG5, REG6, REG7, REG8, REG9, REG10, REG11, REG12 and REG13) output voltage using multimeters, scopes, electric load. 1) Do not turn the power supply on until all connections have been made. 2) Connect jumper J4_0 (V_I/O) to J5_0 (VIN). 4) For the sequencing procedure, refer to the ACT8847 datasheet for more details. 3) Connect jumper J11_3 to J10 to set VSEL to a logic low. 4) Connect jumper J8_0 to J7 to set GPIO1 to a logic low. 5) Connect jumper J8_1 to J7 to set GPIO2 to a logic low. 6) Connect power supply positive lead to the VIN pin connector. 7) Connect power supply negative lead to the GND pin connector. 8) Connect dongle to the computer which has the ACT8847 GUI Software installed. 9) Set the power supply to 3.6V. 10) Turn on the power supply.
