WT8072H

The WT8072H is designed as one kind of PIR (passive infra-red) controller that has some points of features:(1)high noise immunity; (2)drive either relay or triac; (3)adjustable light on duration; (4)triac can be either shunt or serial connected; (5)PIR input; (6)CDS input. This device is the most stable PIR controller you can find on the market. More than this, there are few components needed in its application circuit which can reduce material cost and increase competitive.

The absolute maximum ratings of the WT8072H can be summarized as:(1)power supply vdd with repect to Vss: 5.6 V;(2)voltage on any pin: -0.3 to 5.6 V;(3)operating temperature: 0 to 70 ;(4)storage temperature: -65 to +150 .

The electrical characteristics of WT8072H can be summarized as:(1)supply voltage: 4.2 V to 5.5 V;(2)standy current: 0.9 mA to 1.2 mA;(3)operating current: 1.8 mA to 2.5 mA;(4)stable voltage: 3.0 V to 3.4 V;(5)source current of Vref: 200 uA;(6)CDS output sink current: 11.6 mA to 21 mA;(7)relay source current: 5 mA;(8)relay sink current: 5 mA;(9)relay operating voltage: 13.1 V to 18.8 V;(10)triac sink current: 50 uA.
