The MTD6502B-LC1-02 is a Pulse Width Modulation FET driver for high side applications. It takes a pulse width modulated input signal and drives four N-channel MOSFETs in a half bridge configuration for control of motors, actuators and lighting. The device provides isolation of the control circuitry from the motor supply and the four outputs are fully isolated from each other.

The MTD6502B-LC1-02 is a high-side driver, meaning it can provide drive to the upper or lower sides of dual winding motors without the need for low-side switching. This greatly simplifies system design as this driver can drive a full H-bridge. The device also provides a single wire current sense for load control for precision current limiting and control. The MTD6502B-LC1-02 is designed for use with brushless DC (BLDC) motors and is capable of applications up to 15A.

The MTD6502B-LC1-02 also includes fault-protection features to guarantee safe operation, such as over-voltage protection and over-temperature protection. Additionally, the thermal shutdown threshold has been programmed to 55C.

As an integrated circuit device, the MTD6502B-LC1-02 is designed to be used in battery powered and low-voltage, low-current AC/DC and DC/DC power supplies. It is primarily targeted for the automotive and industrial automation markets. This part is available in a very small 6-lead SOT-563 package, providing a minimal system cost and size while offering excellent power dissipation. This makes it particularly suitable for mobile and space limited applications.

The MTD6502B-LC1-02 can operate in three different modes: PWM, Linear, and Pulse-by-Pulse current limiting. In the PWM mode, the output pulse duration is set based on the input rating from the motor control circuit. In the Linear mode, the output is proportional to the input voltage and current. And finally in the Pulse-by-Pulse current limiting mode, the output current is limited to a preset value that is programmable via a single pin.

The MTD6502B-LC1-02 also includes configurable dead-time between the high-side and low-side outputs as well as adjustable output frequencies up to 200kHz. This means that the device can be used in applications that require high speed operation while still maintaining a high level of efficiency and reliability.

The MTD6502B-LC1-02 is a highly integrated solution that provides a cost effective and reliable solution for driving high side motors and actuators. It is a single chip solution that offers a high level of protection and is easy to use. Its small form factor makes it ideal for space constrained applications and its robust architecture ensures reliability in harsh environments.
