PCA1461 Overview
Key Specifications
Max Voltage (typical range): 2.5 V
Min Voltage (typical range): 1.2 V
Max Operating Temp: 60 °C
Min Operating Temp: -10 °C
Key Features
- 32 kHz oscillator, amplitude regulated with excellent frequency stability
- High immunity of the oscillator to leakage currents
- Time calibration electrically programmable and reprogrammable (via EEPROM)
- A quartz crystal is the only external component required
- Very low current consumption; typically 170 nA
- Output for bipolar stepping motors of different types
- No loss of motor steps possible because of on-chip detection of the induced motor voltage
- Detector for lithium or silver-oxide battery voltage levels
- Indication for battery end-of-life
- Stop function for accurate timing
