1
HVS
High-voltage start-up. The pin, able to withstand 700V, is to be tied directly to the
rectified mains voltage. A 1 mA internal current source charges the capacitor
connected between Vcc pin (5) and GND pin (3) until the voltage on the Vcc pin
reaches the turn-on threshold, then it is shut down. Normally, the generator is re-
enabled when the Vcc voltage falls below 5V to ensure a low power throughput
during short circuit. Otherwise, when a latched protection is tripped the generator is
re-enabled 0.5V below the turn-on threshold, to keep the latch supplied; or, when
the IC is turned off by pin COMP (9) pulled low the generator is active just below
the UVLO threshold to allow a faster restart.
2
N.C.
Not internally connected. Provision for clearance on the PCB to meet safety
requirements.
3
GND
Ground. Current return for both the signal part of the IC and the gate drive. All of
the ground connections of the bias components should be tied to a track going to
this pin and kept separate from any pulsed current return.
4
GD
Gate driver output. The totem pole output stage is able to drive power MOSFET’s
and IGBT’s with a peak current capability of 800 mA source/sink.
