Mnemonic Description
LFCSP WLCSP
14 A3 VIN Input Voltage, 2.5 V to 5.5 V.
3 D3 D1 LED Sink 1.
2 E3 D2 LED Sink 2.
1 E4 D3 LED Sink 3.
20 D4 D4 LED Sink 4.
19 C4 D5 LED Sink 5.
17 B4 D6 LED Sink 6. This pin can also be selected as a comparator input for the second phototransistor.
16 B3 D7 LED Sink 7.
18 C3 CMP_IN
Comparator Input for Phototransistor. When using this function, a capacitor (0.1 µF recommended)
must be connected from this pin to ground.
13 A2 VOUT Charge Pump Output.
11 A1 C1+ Charge Pump C1+.
9 C1 C1−
Charge Pump C1−.
12 B1 C2+ Charge Pump C2+.
10 B2 C2− Charge Pump C2−.
15 A4 GND1 Ground. Connect the exposed pad to GND1 and/or GND2.
8 D1 GND2 Ground. Connect the exposed pad to GND1 and/or GND2.
6 D2 nINT
Processor Interrupt (Active Low). Requires an external pull-up resistor. If this pin is not used, it
can be left floating.
5 E1 nRST
Hardware Reset (Active Low). This pin resets the device to the default conditions. If not used,
this pin must be tied above V
IH(MIN)
.
7 C2 SDA I
2
C Serial Data. Requires an external pull-up resistor.
4 E2 SCL I
2
C Clock. Requires an external pull-up resistor.
21 NA EPAD Exposed Paddle. Connect the exposed paddle to GND1 and/or GND2.
