ACT2803

APPLICATIONS INFORMATION

2. Place the decoupling ceramic capacitor as

close to BAT pin as possible. Use different

capacitance combination to get better EMI

performance.

3. Place the decoupling ceramic capacitors close

to VIN pin, VOUT pin, and BAT pin.

4. Use copper plane for power GND for best heat

dissipation and noise immunity.

5. Connect battery with the sequence of BATN-

>BATP->BATC.

6. Use Kevin sense from sense resistors to CSP

and CSN pins, and the sense resistor from

BATS and BATP pins.

7. SW pad is a noisy node switching. It should be

isolated away from the rest of circuit for good

EMI and low noise operation.

8. Thermal pad is connected to GND layer through

vias. PGND and AGND should be single-point

connected.

9. RC snubber and external Schottky diode across

SW to PGND can be added as needed for

reducing

SW

spike

and

better

EMI

performance.
