PCA1462U 资料标题简介

32 kHz watch circuits with adaptive motor pulse

PCA1462U 资料关键信息

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 induced motor voltage
·Detector for lithium or silver-oxide battery voltage levels
·Indication for battery end-of-life
·Stop function for accurate timing
·Power-on reset for fast testing
·Various test modes for testing the mechanical parts of
the watch and the IC.
