8 / 23 page Picor Corporation • picorpower.com PI2002 Rev1.1 Page 8 of 23 When the input source voltage is applied and before the MOSFET is fully enhanced, a voltage greater than the Forward Over-Current (FOC) Threshold may be present across the MOSFET. To avoid an erroneous FOC detection, a VGS detector blanks the FOC and FWD comparators from initiating a fault, until the GATE pin reaches 45% of VG-CLMP. If VC is too low to establish the Gate Clamp condition the reference for detection is 45% of {VC-V(SN) - 0.25V}. The GATE pin pulls low under the following fault conditions: • Reverse Current • Forward Over-Current “AND” clamp detector is cleared • Over Temperature • Input Under-Voltage • Input Over-Voltage “AND” nominal Forward Current • VC pin Under-Voltage Fault: The fault circuit output is an open collector with 40μs delay to prevent any false triggering. The FT pin will be pulled low when any of the following faults occurs: • Reverse Current • Forward Over-Current “AND” clamp detector is cleared • Forward Low Current “AND” clamp detector is cleared • Over Temperature • Input Under-Voltage • Input Over-Voltage “AND” nominal Forward Current • VC pin Under-Voltage The Forward Current fault condition occurs when the MOSFETs gates are high but are not conducting a significant level of forward current or may indicate the MOSFETs are shorted either internally or externally (VD1-D2 < 6mV). The VGS detector prevents FOC or FWD from initiating a fault when the MOSFET gate is low. The gate to SN voltage has to reach sufficient voltage to establish the Rds(on) condition before these faults are detected. |
