| Description | GENERAL DESCRIPTION PCA146x series The PCA146x series devices are CMOS integrated circuits specially suited for battery-operated, quartz-crystal-controlled wrist-watches, with a bipolar stepping mot... |
| 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 circuits, by self adaption of the motor pulse width to match the required torque of the motor • No loss of motor steps possible because of on-chip detection of the... |
