Figure 4.2 Peak Detection Example  
The peak detector threshold is determined upon device power up by the value of the resistor  
connected between the TH_SEL pin and ground (for EMC1701-1 only) or via the SMBus (see  
Section 5.17). The resistor selects one of 16 different VSENSE measurement limits (from 10mV to  
85mV) as shown in Table 4.1.

The peak detector duration is determined upon device power up by the value of the resistor between  
the DUR_SEL pin and ground (for EMC1701-1 only) or via the SMBus (see Section 5.17). The resistor  
selects one of 16 different time durations from 1 ms to 4.096s as shown in Table 4.2.
