SLA5086 Application Field and Working Principle

The SlA5086 is a transistor array designed and manufactured by Toshiba. This transistor array combines a series of MOSFETs and BJTs in a single package and provides a simple way of providing high power output.

Application Field

The SLA5086 is widely used in motor control, high voltage drive applications and motor control/monitoring systems. It is also used in applications such as power supplies, inverters, automotive audio amplifiers and for other load current control applications. Due to its high output current and switching capability, the SLA5086 is mainly used in power management and motion control applications.

Working Principle

The SLA5086 is a monolithic transistor array consisting of N-channel and P-channel MOSFETs, plus two bipolar transistors. All of the transistors in this device are independently driven, enabling them to be used in various configurations. The current from the power supply is supplied to each of the transistors through an external resistor. The current can then be controlled by varying the external resistance or by changing the voltage on the gate terminal of the transistor. The output current of the device is regulated through the use of a variable resistor, which can be adjusted to limit the current to the required level.

The SLA5086 also features two built-in PN diodes which are used as a voltage clamp. This allows the device to operate safely up to a certain voltage level, avoiding any potential damage due to overvoltage. It also enables the device to provide a wide range of output power levels.

In order to ensure a reliable and efficient operation, the SLA5086 also includes protection circuitry. The circuitry will provide protection against over-current, over-voltage, under-voltage and temperature. In addition, the device is designed to be able to withstand drastic voltage changes and transient voltage spikes, making it a reliable solution for harsh operating conditions.

Conclusion

The SLA5086 provides a cost effective solution for users seeking a reliable, high power transistor array solution. The device’s built-in protection circuitry ensures efficient and safe operation in a variety of operating conditions, while its series of transistors enable it to provide a wide range of output power levels. As such, the SLA5086 is an ideal choice for a wide range of applications including motor control and power management.
