TDA21101G Description

Short technical summary and product information.

The TDA21101G is a dual high-speed driver IC from Infineon Technologies, specifically designed for driving N-channel low-side and high-side MOSFETs. It features a bootstrapping circuit for efficient high-side gate drive and adaptive gate drive control to prevent cross-conduction.

 

This driver supports fast rise and fall times, enabling operation at frequencies up to 2 MHz. It is capable of sinking and sourcing more than 4A peak current, contributing to low switching losses. The operating voltage range is from 5V to 13.2V, and it includes protection features such as over-temperature and UVLO.

 

The TDA21101G is housed in a surface-mount PG-DSO-8 package, making it suitable for high-density applications. Its design is ideal for multi-phase DC-DC converters used in CPU power supplies, VRMs, and notebook CPU supplies, as well as motor drive and Class-D amplifier applications.

 

Key features include adjustable high-side MOSFET gate drive voltage, integration of the bootstrap diode, and a shut-down mode for low quiescent current. It is compatible with standard PWM controllers and offers floating high-side MOSFET drive up to 30V.
