Single-Channel 5-A High-Speed, Low-Side Gate Driver
Detailed Description
Overview
The TPM44273 single-channel low-side gate driver is designed for high-performance power supplies, motor controls, and
inverters. Designed with industrial standard pin-out and package, the TPM44273 accelerates the design process. With
extended voltage ranges on supply voltage and negative input voltage on inputs, the TPM44273 improves system-level
reliability. 5-A Strong driving capability improves gate driver efficiency and lowers heat generation, especially in highfrequency switching applications.

TPM44273
Single-Channel 5-A High-Speed, Low-Side Gate Driver
Feature Description
Low Propagation Delay Driver Output
The low-propagation-delay design allows the device to achieve industrial-leading low propagation delay between device input
and output. The low delay enhances driver performance in high-frequency switching regulators.
Supply and UVLO
The device monitors supply voltage with under-voltage lock-out (UVLO). When the supply voltage is below the UVLO
threshold, the outputs are held low in UVLO to avoid glitches during power rising and falling.
The quiescent current and operating current of the device are measured as shown in Figure 4. The current is related
to internal quiescent current consumption as well as output current. The output current can be calculated using external
transistor gate charge times switching frequency fsw.
Channel Input
The input of TPM44273 gate drivers supports TTL and CMOS input with threshold voltage independent of supply voltage.
The threshold is also designed as temperature-independent to support a wide range of ambient temperatures. Wide
hysteresis enhances system-level noise immunity. The integrated pull-down resistors set the device in a low state when
inputs are floating.
Inputs can withstand DC −5V, to improve robustness on ground bouncing.
Output Stage
The TPM44273 output stage can deliver high current sourcing and sink up to 5-A with low propagation delay.
