EVQ1925-R-00A

EVQ1925-R-00A is a 100V, 4A, high-frequency, half-bridge gate driver evaluation board. It is designed to demonstrate the capabilities of the MPQ1925HR, a high-frequency, half-bridge gate driver. The MPQ1925HR has a 3A source current and a 4.5A sink current at 12V VDD. The quiescent current (IQ) is below 150μA. The MPQ1925HR’s integrated bootstrap (BST) diode reduces the external component count. The device’s low-side MOSFET (LS-FET) and high-side MOSFET (HS-FET) driver channels are independently controlled, and are matched with less than 5ns in time delay. In the case of an insufficient supply, the device’s HS-FET and LS-FET under-voltage lockout (UVLO) protection forces the outputs low. It is designed for motor drivers and other power control applications, such as telecommunication half-bridge power supplies, avionics DC/DC converters, two-switch forward converters, and active-clamp forward converters.
