Features
Pulse width modulation outputs
Two independent outputs: 1x PWM output on ST25DV02K-W1, 2x PWM outputs on ST25DV02K-W2
From 488 Hz to 31250 Hz 62.5 ns pulse width resolution: from 15-bit resolution at 488 Hz to 9-bit
resolution at 31.25 kHz Accuracy: ±10% over temperature range No need for external oscillator Supply
voltage from 1.8 V to 5.5 V, independent from contactless interface Independent push-pull outputs
– Up to 4 mA drive capability per output – Adjustable output drive for low power and low noise application Live update of PWM parameters controlled by contactless interface
Contactless interface
Based on ISO/IEC 15693 and NFC Forum Type 5 Tag Supports all ISO/IEC 15693 modulations, coding, sub-carrier modes and data
