Under Voltage Lockout Feature. (Discussion applies to
HCPL-3120, HCPL-J312, and HCNW3120)
The HCPL-3120 contains an under voltage lockout (UVLO)
feature that is designed to protect the IGBT under fault
conditions which cause the HCPL-3120 supply voltage
(equivalent to the fully-charged IGBT gate voltage) to
drop below a level necessary to keep the IGBT in a low re-
sistance state. When the HCPL-3120 output is in the high
state and the supply voltage drops below the HCPL-
3120 V
coupler output will go into the low state with a typical
delay, UVLO Turn Off Delay, of 0.6 µs.
When the HCPL-3120 output is in the low state and
the supply voltage rises above the HCPL-3120 V
threshold (11.0 < V
will go into the high state (assumes LED is “ON”) with a
typical delay, UVLO Turn On Delay of 0.8 µs.

IPM Dead Time and Propagation Delay Specifications.
(Discussion applies to HCPL-3120, HCPL-J312, and
HCNW3120)
The HCPL-3120 includes a Propagation Delay Difference
(PDD) specification intended to help designers minimize
“dead time” in their power inverter designs. Dead time
is the time period during which both the high and low
side power transistors (Q1 and Q2 in Figure 25) are off.
Any overlap in Q1 and Q2 conduction will result in large
currents flowing through the power devices between
the high and low voltage motor rails.
