Overview
The TD310IN, produced by STMicroelectronics, is a triple IGBT/MOS driver with current sense capabilities. It is designed to drive one, two, or three power IGBTs or MOSFETs and also has the capability to drive pulse transformers. This makes it highly suitable for interfacing control ICs with power switches in low-side or half-bridge configurations. The device includes a current sense comparator that inhibits the output drivers in case of overcurrent, and an alarm output signals this event to a controller. Additionally, it features an uncommitted op-amp that can be used for current measurement or other general-purpose applications. The TD310IN supports programmable undervoltage lockout and standby mode, making it versatile for various environmental and application conditions.
