EV1909-TL-00A

EV1909-TL-00A is an evaluation board designed to demonstrate the capabilities of the MP1909, a high-frequency, half-bridge, N channel power MOSFET gate driver. Its high side (HS) and low-side (LS) driver channels are controlled via a signal input. If the enable (EN) pin is pulled low, both the HS and LS outputs are disabled. Internal dead time (DT) control reduces switching power losses and prevents shoot through. The integrated bootstrap (BST) diode reduces the external component count. Full protection features include under-voltage lockout (UVLO) protection and thermal shutdown. The MP1909 is available in an SOT583-8 (1.6mmx2.1mm) package. Typical applications include wireless charging, E-cigarettes, drones, avionics DC/DC converters and active-clamp forward converters.
