The UCC27614-Q1 is a single channel, high-speed, low-side gate driver capable of effectively driving MOSFET, IGBT, SiC, and GaN power switches. The UCC27614-Q1 has a typical peak drive strength of 10A, which reduces the rise and fall times of the power switches, lowering switching losses and increasing efficiency. The small propagation delay of the UCC27614-Q1 yields better power stage efficiency by improving dead-time optimization, pulse width utilization, control loop response, and transient performance of the system.
The UCC27614-Q1 can handle –10V on its inputs, which improves robustness in systems with moderate ground bouncing. The inputs are independent of supply voltage and can be connected to most controller outputs for maximum control flexibility. An independent enable signal allows the power stage to be controlled independent of the main control logic. The gate driver can quickly shut off the power stage if there is a fault in the system (which requires the power train to be turned off). The enable function also improves system robustness. Many high-frequency switching power supplies exhibit high frequency noise at the gate of the power device, which can get injected into the output pin of the gate driver and can cause the driver to malfunction. The UCC27614-Q1 performs well in such conditions due to its transient reverse current and reverse voltage capability.
The strong internal pulldown MOSFET holds the output low if the VDD voltage is below the specified UVLO threshold. This active pulldown feature further improves system robustness. The 10A drive current of the UCC27614-Q1 in the 2mm × 2mm package improves system power density. This small package also enables optimum gate driver placement and improved layout.
