IR2112 MOSFET DRIVER
Share :
The IR2112 is a high-speed, high-voltage Half-Bridge Gate Driver Integrated Circuit (IC).
Its core specifications and relevance are:
Type: High- and Low-Side Gate Driver.
Voltage Rating (V_OFFSET): Capable of driving high-side power switches with up to 600 V offset voltage, providing the necessary high dielectric strength and electrical separation required by the safety text.
Output Current (I_O): Features high peak output current (typically 2 A) to ensure fast turn-on and turn-off of large MOSFETs or IGBTs (like the K75T60 or 55NM60AD), which is essential for achieving the high efficiency goals.
Topology: Designed specifically to drive the half-bridge power stage, using a bootstrap circuit to power the floating high-side gate driver.
Logic: Provides separate logic inputs for the high-side and low-side outputs, often including built-in dead-time functionality to prevent simultaneous conduction (shoot-through) of the switches. This directly supports the inverter's Protection requirement by avoiding catastrophic thermal failure and meeting the 120C safety threshold.
Package: Typically available in DIP-14.
