Description
chip with bumps on tape chip with bumps on tape chip on foil chip on foil GENERAL DESCRIPTION
PCA148x series
No loss of motor steps possible because of on-chip detection of the induced motor voltage
Indication for battery end-of-life
Stop function for accurate timing
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.
- Up to 50% reduction in motor current compared with conventional circuit.
