Texas Instruments SN6501 | Demoboard TIDA-00794
Automotive Low-Noise 350 mA, 410 kHz Transformer Driver
Overview
| Topology | Push-Pull Converter symmetrical isolated |
| Input voltage | 5 V |
| Output 1 | 5 V / 0.15 A |
| IC revision | E1 |
Description
The SN6501-Q1 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-Q1 consists of an oscillator followed by a gate drive circuit that provides the complementary output signals to drive the ground referenced N-channel 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.
