TEA2209T

Active bridge rectifier controller

Rev. 1.1 — 14 April 2021

Product data sheet

1 General description

The TEA2209T is a product of a new generation of active bridge rectifier controllers

replacing the traditional diode bridge.

Using the TEA2209T with low-ohmic high-voltage external MOSFETs significantly

improves the efficiency of the power converter as the typical rectifier diode-forward

conduction losses are eliminated. Efficiency can improve up to about 1.4 % at 90 V (AC)

mains voltage.

The TEA2209T is designed in a silicon-on insulator (SOI) process.

2 Features and benefits

2.1 Efficiency features

• Forward conduction losses of the diode rectifier bridge are eliminated

• Very low IC power consumption (2 mW)

2.2 Application features

• Integrated high-voltage level shifters

• Directly drives all four rectifier MOSFETs

• Very low external part count

• Integrated X-capacitor discharge (2 mA)

• Self-supplying

• Full-wave drive improving total harmonic distortion (THD)

• S016 package

2.3 Control features

• Disable function for all external power FETs

• Undervoltage lockout (UVLO) for high-side and low-side drivers

• Drain-source overvoltage protection for all external power MOSFETs

• Gate pull-down currents at start-up for all external power MOSFETs
