Monolithic Power Systems (MPS) MPQ18811 AEC-Q100 Single-Channel Gate Drivers
Monolithic Power Systems (MPS) MPQ18811 AEC-Q100 Single-Channel Gate Drivers are isolated high-performance solutions designed for automotive applications. The MPS MPQ18811 features up to 6A of source and 10A of sink peak current capacity, making the devices ideal for driving power-switching devices with minimal propagation delay and pulse-width distortion. Utilizing capacitive-based isolation technology, the MPQ18811 provides a reinforced isolation voltage up to 5kVRMS and boasts a common-mode transient immunity (CMTI) rating above 150kV/μs. The driver operates efficiently across a wide input voltage range of 2.8V to 5.5V on the primary side and up to 30V on the secondary side. With integrated protection features such as under-voltage lockout (UVLO) and an internal active Miller clamp, the MPQ18811 ensures robust performance in demanding environments. Available in SOIC-8 narrow-body (NB) and wide-body (WB) packages, these gate drivers are certified to meet stringent automotive standards.
