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.
3 ^{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
4 ^{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.
