resistor Rf.
A3 3 I INP Positive input of the first amplifier, receives the common mode voltage.
B1 NA I VM_P Power Analog Ground.
B2 7 I VM Core Analog Ground.
B3 6 I V
p
Positive analog supply of the cell. Range: 2.5 V-5.5 V.
C1 2 I BYPASS Bypass capacitor pin which provides the common mode voltage (Vp/2).
C2 8 O OUTB Positive output of the NCP2890. Connected to the load.
C3 1 I SHUTDOWN The device enters in shutdown mode when a low level is applied on this pin.
