offset of the UC1854A/B guarantees that the PWM circuit
will not drive the MOSFET if the current command is zero
(both Current amplifier inputs zero.).Previous designs
required an external offset cancellation network to
implement this key feature. The bandwidth of the Current
Amplifier has been improved as well to 5mHz typical.
While this is not generally an issue at 50 or 60Hz inputs, it
is essential for 400Hz input avionics applications.
MISCELLANEOUS
Several
other
important
enhancements
have
been
implemented in the UC1854A/B. A VCC supply voltage
clamp at 20V allows the controller to be current fed if
desired. The lower startup supply current (250
A typical),
substantially reduces the power requirements of an offline
startup resistor. The 10.5/10V UVLO option (UC1854B)
enables the controller to be powered off of an auxiliary
12V supply.
The VREF "GOOD" comparator guarantees that the
MOSFET driver output remains low if the supply or the
7.5V reference are not yet up. This improvement
eliminates the need for external Schottky diodes on the
PKL and CA+ pins that some UC1854 designs require.
The propagation delay of the disable feature has been
improved to 300ns typical. This delay was proportional to
