Pin Description (continued)

NAME

FUNCTION

TOPSEL

Input to Indicate Topmost Device in the Daisy Chain. This pin should be connected to AGND for all devices

except the topmost. For the top device, this pin should be connected to VAA.

ALRMU

Upper Port Alarm Input. This input receives the ALRML output signal from an upper neighboring module. It

swings between VDDU and GNDU.

GNDU

Level-Shifted Upper Port Ground. Upper port-supply return and supply input for the charge pump and HV

supplies. This pin should be connected to the DCIN takeoff point on the battery stack as shown in the

application diagrams.

VDDU

Level-Shifted Upper Port Supply. Upper port-supply output for the daisy-chained bus. This is a regulated

output voltage from the internal charge pump that is level-shifted above the DCIN pin voltage level. It

should be bypassed with a 1µF capacitor to GNDU.

37, 38

CP-, CP+

Charge-Pump Capacitor. Negative/positive input for the internal charge pump. Connect a 0.01µF high-

voltage capacitor between CP+ and CP-.
