Output Stage

The output stages of the UCC53x0 family feature a pull-up structure that delivers the highest peak-source current when it is most needed which is during the Miller plateau region of the power-switch turn-on transition (when the power-switch drain or collector voltage experiences dV/dt). The output stage pull-up structure features a P-channel MOSFET and an additional pull-up N-channel MOSFET in parallel. The function of the N-channel MOSFET is to provide a brief boost in the peak-sourcing current, which enables fast turn-on. Fast turn-on is accomplished by briefly turning on the N-channel MOSFET during a narrow instant when the output is changing states from low to high. Table 8-1 lists the typical internal resistance values of the pull-up and pull-down structure.

Table 8-1 UCC53x0 On-Resistance
DEVICE OPTION RNMOS ROH ROL RCLAMP UNIT
UCC5320SC and UCC5320EC 4.5 12 0.65 Not applicable Ω
UCC5310MC 4.5 12 1.3 1.3 Ω
UCC5390SC and UCC5390EC 0.76 12 0.13 Not applicable Ω
UCC5350MC 1.54 12 0.26 0.26 Ω
UCC5350SB 1.54 12 0.26 Not applicable Ω

The ROH parameter is a DC measurement and is representative of the on-resistance of the P-channel device only. This parameter is only for the P-channel device, because the pull-up N-channel device is held in the OFF state in DC condition and is turned on only for a brief instant when the output is changing states from low to high. Therefore, the effective resistance of the UCC53x0 pull-up stage during this brief turn-on phase is much lower than what is represented by the ROH parameter, which yields a faster turn-on. The turn-on-phase output resistance is the parallel combination ROH || RNMOS.

The pull-down structure in the UCC53x0 S and E versions is simply composed of an N-channel MOSFET. For the M version, an additional FET is connected in parallel with the pull-down structure when the CLAMP and OUT pins are connected to the gate of the IGBT or MOSFET. The output voltage swing between VCC2 and VEE2 provides rail-to-rail operation.
