Register 46 April 2, 2013
DetectTh1
Channel 1 Current Threshold in Detection Mode
DetectTh2
Channel 2 Current Threshold in Detection Mode
Address: 11H
Type: Read/Write
Default Value: 0000H
Bit Name Description
15 - Reserved.
14:8 CalCodeN
Channel 1 current negative detector calculation code.
Code mapping:
7'b000-0000, Vc=-4.28mV=-3.03mVrms (Vc is the threshold of low power computation)
7'b111-1111, Vc=12.91mV=9.14mVrms
DAC typical resolution is [12.91-(-4.28)]/127=135.4μV=95.7μVrms
7-Reserved.
6:0 CalCodeP
Channel 1 current positive detector calculation code.
Code mapping:
7'b000-0000, Vc=-4.28mV=-3.03mVrms (Vc is the threshold of low power computation)
7'b111-1111, Vc=12.91mV=9.14mVrms
DAC typical resolution is [12.91-(-4.28)]/127=135.4μV=95.7μVrms
