The UCC27528-Q1 device is a dual-channel, high-speed, low-side gate driver capable of
effectively driving MOSFET and IGBT power switches. Using a design that inherently minimizes
shoot-through current, the UCC27528-Q1 device can deliver high-peak current pulses of up to 5-A
source and 5-A sink into capacitive loads along with rail-to-rail drive capability and extremely
small propagation delay of 17 ns (typical). In addition, the drivers feature matched internal
propagation delays between the two channels which are very well suited for applications requiring
dual-gate drives with critical timing, such as synchronous rectifiers. The input pin thresholds are
based on CMOS logic, which is a function of the VDD supply voltage. Wide hysteresis between the
high and low thresholds offers excellent noise immunity. The enable pins are based on TTL and CMOS
compatible logic, independent of the VDD supply voltage.
The UCC27528-Q1 device is a dual noninverting driver. Internal pullup and pulldown
resistors on the input pins of the UCC27528-Q1 device ensure that outputs are held low when input
pins are in floating condition. The UCC27528-Q1 device features enable pins (ENA and ENB) for
better control of the operation of the driver applications. The pins are internally pulled up to
the VDD supply for active-high logic and can be left open for standard operation.
