GENERAL DESCRIPTION
The TC96C555 Power Oscillator is an easily pro-
grammed IC that can be used in simple switch-mode power
supplies, diode doublers and inverters, and similar circuits
where high-current pulses are needed in an economical
form.
The TC96C555 uses TelCom Semiconductors' new
Tough CMOS process. The output drive capability is
similar to the TC4423/4/5 MOSFET Drivers, which can
switch in 25nsec into a capacitive load of 1,800pF. The
TC96C555 will not latch up under any conditions within their
power and voltage ratings. They can accept, without dam-
age, up to 1.5A of reverse current (of either polarity) being
forced back into the output. All terminals are also fully
protected against up to 4kV of electrostatic discharge. The
peak output is rated at 3A. Split outputs permits driving of an
external pair of MOSFETS, with controllable cross conduc-
tion between upper and lower devices.
