High-Side Current-Sense and Internal 1°C Temperature Monitor

Datasheet

SMSC EMC1701

Revision 1.2 (09-27-10)

DATASHEET

Bits 5 - 4 - CS_SAMP_AVG[1:0] - Determines the number of averages that the Current Sensing

Circuitry will take as shown in Table 5.22.

Bits 3 - 2 - CS_SAMP_TIME[1:0] - Determines the sampling time of the Current Sensing Circuitry as

shown in Table 5.23. The VSENSE voltage will be updated at this rate representing the average current

over the Sampling Time multiplied by the Averaging factor as shown in Table 5.24.
