Table 6-2 Pin Functions Generic
PIN I/O DESCRIPTION
NAME NO.
VDD 1 I Input Supply Voltage.
SENSE1 2 I Input for the monitored supply voltage rail channel 1
SENSE2 3 I Input for the monitored supply voltage rail channel 2
RESET1 RESET1, 4 O Output Reset Signal For Channel 1: See Figure 5-1
RESET2 RESET2, 5 O Output Reset Signal For Channel 2: See Figure 5-1
CTR1/ MR 6 _

Capacitor Time Delay Reset 1. The CTR1 pin offers a user-programmable reset release delay for Reset1. Connect an external capacitor on this pin to adjust time delay. When not in use leave pin floating for the fastest time delay.

Manual Reset (CTR1/ MR):If this pin is driven low the RESET1 output will reset, leave pin floating or connected to a cap to release reset. This pin should not be driven high.
CTR2/ MR 9 _ Capacitor Time Delay Reset 2. The CTR2 pin offers a user-programmable reset release delay for Reset2. Connect an external capacitor on this pin to adjust time delay. When not in use leave pin floating for the fastest time delay.

Manual Reset (CTR2/ MR):If this pin is driven low the RESET2 output will reset, leave pin floating or connected to a cap to release reset. This pin should not be driven high.
GND 10 _ Ground
NC PAD - Not internally connected, is recommended to leave the central pad floating for wider creepage between VDD and GND.
CTS1 7 _ Capacitor Time Delay Sense 1. The CTS1 pin offers a user-programmable sense delay for Sense1. Connect an external capacitor on this pin to adjust time delay. When not in use leave pin floating for the fastest time delay.
CTS2 8 _ Capacitor Time Delay Sense 2. The CTS2 pin offers a user-programmable sense delay for Sense2. Connect an external capacitor on this pin to adjust time delay. When not in use leave pin floating for the fastest time delay.
