COSINE Tier-1 distributor Jarwey｜Push-pull transformer drivers COS6501/6505B for isolated I/O

Jarwey is a Tier-1 distributor of COSINE—selection support, datasheets, sampling & small batch, lead-time coordination.

COSINE push-pull transformer drivers target low-power isolated supplies for CAN / RS-485 / RS-232 / SPI / I2C. Evaluate COS6501 / COS6505B as SN6501 / SN6505B second-source paths. External-FET PWM controllers (UC384x / SG3525 class) are covered in the PWM family article—not repeated here.

Checklist before freeze

1. Bus type: CAN / 485 / 232 / SPI / I2C load current on the secondary.
2. Transformer: turns ratio, leakage, saturation vs vendor transformer table.
3. Standby / EMI: does COS6501 fit low-standby; switching behavior acceptable?
4. Footprint: SOT-23-5 vs SOT-23-6, decoupling, creepage.
5. Samples: request datasheet & samples from Jarwey.
