VCCSENSE
By connecting a very low value (m&) current sense resistor between these two
pins, the MIC2310s internal primary and secondary overcurrent detection
circuits monitor the load current. The VCCSENSE pin is the positive (+) input
terminal and the SENSE pin is the negative (-) input terminal of the overcurrent
detection circuits. If the voltage across the sense resistor exceeds either the
primary overcurrent threshold for a time (t
POC
) or the secondary primary
overcurrent threshold for any duration, the MIC2310 electronic circuit breaker is
tripped, the GATE is turned OFF, the DISCH circuit is activated, and the I_FLT
digital output is asserted. The controller also incorporates a patent-pending built-
in test for shorted current-sense resistors. Because of this built-in self test, the
MIC2310s electronic circuit breaker cannot be disabled by connecting together
the VCCSENSE and SENSE pins.

VCC
Positive supply input to the MIC2310. The MIC2310 is specified to operate from
+10.8V d V
CC
 d +13.2V and the supply current with ENABLE = HIGH is less than
10mA.
