Low-height package products allow bufferless direct drive of low-to-medium-power IGBTs and MOSFETs from microcontrollers
TOKYO—Toshiba Corporation’s (TOKYO: 6502) Storage & Electronic Devices Solutions Company today announced the launch of a series of low-input current drive, rail-to-rail output, gate-drive photocouplers in a low-height package that allows bufferless direct drive of low- to medium-power IGBTs and MOSFETs from microcontrollers. Shipments of the three new products; “TLP5771”, “TLP5772” and “TLP5774” start from today.
With a threshold input current of 2mA (max), half the 4mA (max) of Toshiba’s existing products[1], the new photocouplers allow bufferless direct drive of low- to medium-power IGBTs and MOSFETs from microcontrollers. The new line-up is available in three levels of peak output currents, 1A, 2.5A and 4A, ensuring they meet a wide range of user requirements.
The new photocouplers have rail-to-rail output and also reduces the operation voltage to 10V (min) against the 15V (min) of Toshiba’s existing products[１], which can contribute to higher system efficiency and lower power consumption. Furthermore, the 2.3mm low-height SO6L package can contribute to the development of thinner and smaller systems. Main applications include servo amplifiers, small motor drivers, general-purpose inverters, photovoltaic (PV) inverters and industrial sewing machines.
