3-V Supply: 150 mA (Max) • Low Ripple on Rectified Output Permits Small Output Capacitors • Small 5-Pin SOT-23 Package 2 Applications • Isolated Interface Power Supply for CAN, RS-485, RS-422, RS-232, SPI, I2C, Low-Power LAN • Industrial Automation • Process Control • Medical Equipment 3 Description The SN6501-Q1 is a monolithic oscillator/powerdriver, specifically designed for small form factor, isolated power supplies in isolated interface applications.
The device drives a low-profile, centertapped transformer primary from a 3.
3-V or 5-V DC power supply.
The secondary can be wound to provide any isolated voltage based on transformer turns ratio.
The SN6501-Q1 consists of an oscillator followed by a gate drive circuit that provides the complementary output signals to drive the ground referenced Nchannel power switches.
The internal logic ensures break-before-make action between the two switches.
The SN6501-Q1 is available in a small SOT-23 (5) package, and is specified for operation at temperatures from –40°C to 125°C.
