Function
1HVS
High-voltage start-up. The pin, able to withstand 700 V, 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 5 V to ensure a low power throughput
during short circuit. Otherwise, when a latched protection is tripped the generator is
re-enabled 0.5 V 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.
2N.C.
Not internally connected. Provision for clearance on the PCB to meet safety
requirements.
3GND
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.
4GD
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.
