Overview
The TD310ID, 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 driver is particularly suited for interfacing control ICs with power switches in low-side or half-bridge configurations. The TD310ID 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 operational amplifier that can be used for current measurement or other general-purpose applications. The device supports programmable undervoltage lockout and standby mode, making it versatile for various environmental and application conditions.
