MP1909 - 2A Half-Bridge Gate Driver

General Description

The MP1909 is a high-frequency, 30V, halfbridge, N-channel power MOSFET driver.

Its low-side and high-side driver channels are controlled by a signal input.

Internal adaptive dead time control circuitry reduces the switching power loss and prevents shoot-through.

Key Features

  • Drives N-Channel MOSFET Half-Bridge.
  • Up to 50V VBST Voltage.
  • 4.5V to 12V Gate Drive Voltage.
  • On-Chip Bootstrap Diode.
  • Up to 2.2MHz Switching Frequency.
  • One PWM Signal Generates Both Drives.
  • Low Quiescent Current.
  • 100% Duty Support.
  • UVLO for High-Side and Low-Side Gate Drives.
  • Available in an 8-Pin SOT583 (1.6mmx2.1mm) Package.

DESCRIPTION The MP1909 is a high-frequency, 30V, halfbridge, N-channel power MOSFET driver. Its low-side and high-side driver channels are controlled by a signal input. Internal adaptive dead time control circuitry reduces the switching power loss and prevents shoot-through. Both outputs are disabled when the EN pin is pulled low. The integrated bootstrap diode reduces external component count. Undervoltage lockout (UVLO) functionality protects the IC from operating at insufficient power supplies. Thermal shutdown protection functions can protect the IC from over-temperature conditions.
