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.
