3) Supply voltage(VDD) is powered up and detection voltage(VIN) increases separately from VDD (POL = “L”)
When VIN voltage reaches to the detection voltage (VDETH), the OUT pin outputs VDD voltage.
4) Supply voltage(VDD) is powered up and detection voltage(VIN) decreases separately from VDD (POL = “L”)
When VIN voltage is higher than VDETH, the OUT pin outputs VDD. When VIN goes under the detection voltage (VDETL), the OUT pin outputs VSS. Figure 4. Voltage detection function, VIN is controlled separately from VDD, POL= “L” OUT pin polarity is control ed by POL pin. Table 2 shows MOSSETs output status and OUT pin polarity. Table 2. OUT pin polarity
