Frequently Asked Questions
What is the peak output current of the TPS2811DG4?
The TPS2811DG4 provides a 2A nominal peak output current from its totem-pole output stage, enabling fast charging and discharging of MOSFET gate capacitances. This high peak current reduces MOSFET switching losses by minimizing transition times, which is essential for efficient high-frequency power conversion applications.
What input logic does the TPS2811DG4 use?
The TPS2811DG4 uses Schmitt trigger inputs with a NAND gate-based interface, providing hysteresis for noise immunity and compatibility with PWM controller outputs. The NAND gate input configuration also enables hardware enable/disable control by tying one input high or low, offering simple on/off gate drive control without additional logic circuits.
What supply voltage does the TPS2811DG4 require?
The TPS2811DG4 requires an 8V to 40V regulator input supply in addition to its logic supply for the high-side driver bootstrap or gate drive rail. This wide voltage range allows use with various DC power bus voltages common in industrial, automotive, and telecom power supply designs operating from 12V, 24V, or 48V bus systems.
What are typical applications for the TPS2811DG4?
Typical applications include MOSFET gate driving in synchronous buck converters, half-bridge and full-bridge power stages, class-D amplifiers, motor H-bridge drivers, and high-frequency LLC resonant converters. The dual channel inverting drive is particularly useful for generating complementary gate signals in synchronous rectification and push-pull converter topologies.
What package does the TPS2811DG4 use?
The TPS2811DG4 is housed in an SOIC-8 package (JESD-30 Code: R-PDSO-G8), an 8-pin small-outline surface-mount package. This compact and widely supported package simplifies PCB layout for dual-channel gate driver designs and is compatible with standard automated assembly and reflow soldering processes.
