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/CMP_IN2 LED Sink 6/Comparator Input for Second Phototransistor. When using this pin as a second
phototransistor input, a capacitor (0.1 μF recommended) must be connected from this pin to ground.
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 bit resets the device to the default conditions. If not used, this pin
must be tied above V
IH(MIN)
