Quick Start Operating Procedur e

The following procedure should be used when

operating the ACT8847EV for the first time to verify

correct operation.

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).

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.

System start up/verify REGx operatio n on EV

Board

The following procedure must be followed to

evaluate the IC operation.

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.

2) Released push-button when PWRHLD pin and

PWREN pin has already connected to V_I/O.

3) Verify REGx (REG1, REG2, REG3, REG4,

REG5, REG6, REG7, REG8, REG9, REG10,

REG11, REG12 and REG13) output voltage

using multimeters, scopes, electric load.

4) For the sequencing procedure, refer to the

ACT8847 datasheet for more details.

FEATURES

• Fully Assembled and Tested PCB

• Allows Simple Evaluation of the ACT8847

• Probe Points for Easy Measurement

GENERAL DESCRIPTION

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.
