NGD4300DD-Q100 Series

The NGD4300-Q100 is a high-performance gate driver designed to drive both high-side and low-side N-channel MOSFETs in a synchronous buck or a half-bridge configuration. The floating high-side driver can work with rail voltages up to 120 V and uses a bootstrap supply with an integrated diode. Both low-side and high-side output drivers have an independent undervoltage lockout (UVLO) circuit which disables the output driver when the driver supply is below its threshold level. The NGD4300-Q100 accepts input control signals complying with both TTL and CMOS signaling as low as 2.5 V (±10%). The low voltage, provided by an internal voltage regulator, is used to supply circuitry in signal paths controlling the low-side and high-side power switches. This enables a low-power operation and a better controlled driver performance irrespective of the IC supply voltage.
