3-V or 5-V supply • High primary-side current drive: – 5-V Supply: 350 mA (Max) – 3.
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 is a monolithic oscillator/power-driver, specifically designed for small form factor, isolated power supplies in isolated interface applications.
The device drives a low-profile, center-tapped 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 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 is available in a small SOT-23 (5) package, and is specified for operation at temperatures from –40°C to 125°C.
