TC4451VOA is a low-power gate drive IC specifically designed for power switches, such as IGBTs and MOSFETs. It is a member of a family of products from Texas Instruments (TI) targeting the power management and industrial market. The IC offers an integrated solution for power conversion and amplification of low voltage signals that interface with high voltage switches.

The applications for the TC4451VOA include motor drives, LED drivers, and consumer electronics, such as set-top boxes and televisions. The device is suitable for low power AC or DC drives which require high power levels from a low voltage drive signal. The TC4451VOA specifically has two independent gate drivers, each of which can be configured to drive any two pairs of IGBTs or MOSFETs, with every channel having a dedicated sink and source that make it suitable for full-bridge configurations.

The device offers a high-output drive current up to 2A and peak sink current of 3.5A. It offers a high slew rate of 200V/µs and adjustable dead time for each channel, enabling fast switching speed and improved efficiency. Additionally, the low rise and fall times can be used to minimize the electromagnetic interference (EMI) generated from the device.

The device includes two independent gate drivers, each of which has a dedicated sink and source that make it suitable for full-bridge configurations. The output drivers are powered by a 5V internal regulator and UVLO prevents false turn-on of the gate drive. An externally adjustable dead time and adjustable pre-driver boost voltage further increases the flexibility of the device. The device itself is protected against short-circuits and over-temperature conditions.

The two channels of the output driver are controlled by the input logic signals, which can be low voltage or low power signals. The TC4451VOA accepts logic-level signals from any type of microcontroller, FPGA, DSP or other logic devices with the output voltage ranging from 3.5V to 5.5V. In addition, the device supports the use of low resistor pull up for improved noise immunity.

The operating temperature range for the TC4451VOA is from -40 to +125 °C, and the package size is 12-pin VQFN (very-small-outline-package-no-lead). The device meets safety standards for automotive and industrial applications, such as EMC and ESD. The device is RoHS compliant and is available in industrial temperature grades. This device offers an ideal gate drive solution for low voltage, low power IGBT and MOSFETs.
