DESCRIPTION

The MPQ1925 is a high-frequency, N-channel

MOSFET, half-bridge gate driver. 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. The

MPQ1925 also features an integrated bootstrap

(BST) diode to reduce the external component

count.

The MPQ1925 is available in a QFN-8

(4mmx4mm) package.
