PMIC - Gate Drivers

The 2SP0115T2B0-12 devices are isolated gate drivers from Toshiba, designed for power N-channel power MOSFETs and IGBTs in wide-range PWM applications. Primarily designed for motor drive gate drivers, these devices are also applicable for automotive, industrial and other devices.

Applications

2SP0115T2B0-12 gate drivers have been designed for several applications such as motor drives, petroleum earth moving machineries and industrial equipment. The main features are:

• High efficiency motor control
• High switching frequency
• Simple connection
• Low startup electric current
• Low EMI radiation
• Low base current consumption
• High voltage drive capability

These devices come with highly presented short circuit protection as well as over-voltage protection and high temperature shut down. Additionally, they are also immune against EFT radiation. Moreover they come with selector switch of both package type to fulfil the needs of different application.

Working Principle

The 2SP0115T2B0-12 isolated gate drivers can drive up to 3 power MOSFETs or IGBTs. They come with two floating outputs which allows for more torque, higher efficiency and faster switching cycles. Each floating output is isolated from the other and from the inputs, which makes it ideal for motor drives that require backup systems.

The floating outputs are driven by active switches that are controlled by current sourcing at the inputs. This means that for each bit input, the voltage level has to exceed a certain value before the current driver is activated. In this way, the device can operate at very high switching frequencies with low power losses, making them ideal for use in applications such as motor drives, petroleum earth moving machineries and industrial equipment.

The device also comes with several other features that make it suitable for different applications. For example, it has an integrated watchdog timer which can be used to detect faults in the system and prevent the output from being affected by them. It also has a built-in short circuit protection which ensures that the device will not be damaged if shorts occur. Finally, the device comes with a high voltage drive capability which enables the device to be used in applications where the input voltage is higher than the output voltage.

Conclusion

The 2SP0115T2B0-12 isolated gate drivers from Toshiba are ideal for applications such as motor drives, petroleum earth moving machineries and industrial equipment. They come with a wide range of features such as high switching frequencies, low power losses, and high voltage drive capability, making them ideal for such applications. They also have several built-in safety features such as an integrated watchdog timer and short-circuit protection to protect the device from possible faults. Finally, the device can be used in systems requiring backup systems due to their two floating outputs.
