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.
