Table 3. Pin Function Descriptions
Pin No. Mnemonic Description
1 FALT Open Collector (Active Low) Logic Output. Indicates an overcurrent or overtemperature condition.
2 VSET APD Bias Voltage Setting Input. Short to VPLV for supply tracking mode.
3 VPLV Low Voltage Supply, 4 V to 6 V.
4, 5 VPHV High Voltage Supply, 10 V to 80 V.
6 VCLH Can be shorted to VPHV for extended linear operating range. No connect for supply tracking mode.
7, 9 GARD
Guard pin tracks VAPD pin and filters setpoint buffer noise (with External Capacitor C
GRD
to COMM). Optional
shielding of VAPD trace. Capacitive load only.
8 VAPD APD Bias Voltage Output and Current Input. Sources current only.
10, 12 NC Optional shielding of IPDM trace. No connection to die.
11 IPDM Photodiode Monitor Current Output. Sources current only. Current at this node is equal to I
