ZHCS096C February 2011 – July 2024 UCC27200A , UCC27201A
PRODUCTION DATA
The input stages provide the interface to the PWM output signals. The input impedance of the UCC27200A is 200k? nominal and input capacitance is approximately 4pF. The 200k? is a pulldown resistance to Vss (ground). The CMOS-compatible input of the UCC27200A provides a rising threshold of 6V and falling threshold of 5.6V. The inputs of the UCC27200A are intended to be driven from 0 to VDD levels.
The input stages of the UCC27201A incorporate an open-drain configuration to provide the lower input thresholds. The input impedance is 68k? nominal and input capacitance is approximately 4pF. The 68k? is a pulldown resistance to VSS (ground). The logic level compatible input provides a rising threshold of 2.3V and a falling threshold of 1.6V.
