IS801 Transformer Driver for Isolated Power Supplies 1. FEATURES 3. DESCRIPTION • Push-pull driver for small transformers • Single 3.3V or 5V supply • High primary-side current drive: 5V supply: 500mA (max) 3.3V supply: 500mA (max) • Low ripple on rectified output permits small output capacitors The IS801 is a monolithic oscillator/power-driver, which is designed for small form factor, isolated power supplies in isolated interface applications. A low-profile, center-tapped transformer primary from a 3.3V or 5V DC power supply can be driven by IS801 while the secondary can be wound to provide any isolated voltage based on transformer turns ratio. • VCC undervoltage detect • Spread spectrum clocking for EMI • Thermal shutdown protection • Small SOT23-5 package The IS801 provides the complementary output signals to drive the ground referenced N-channel power switches. In addition to internal breakbefore-make logic between two switches, the IS801 is also integrated with VCC undervoltage protection and thermal shutdown protection. The added spread spectrum clocking can help pass the system EMI test. 2. APPLICATIONS • Isolated interface power supply for CAN, RS485, RS-422, RS-232, SPI, I2C, Low-Power LAN • Industrial automation • Process control • Medical equipment The IS801 is available in a small SOT23-5 package, and is specified for operation at temperatures from –40°C to 125°C.
