TA6009FN 2001-11-09 1 toshiba bipolar linear integrated circuit silicon monolithic TA6009FN shock sensor ic (1 ch version) TA6009FN detects an existence of external shock through the shock sensor and output. features TA6009FN operates from 2.7 to 5.5 v dc single power supply voltage. signal from the shock sensor is amplified according to setting gain, and is detected through the internal window comparator. TA6009FN incorporates 1-ch shock detecting circuitry. input terminal of sensor signal is designed high impedance. differential input impedance = 100 m ? (typ.) lpf (low pass filter) circuitry is incorporated. cut-off frequency of lpf = 7 khz sensitivity of shock detection can be adjusted by external devices. small package ssop10-p-0.65a (0.65 mm pitch) block diagram pin connection (top view) weight: 0.04 g (typ.) w-cont 10 do a i a o v cc 9 8 7 6 si a 1 2 3 4 5 sib guard out gnd 3 4 7 8 9 10 6 v cc 5 gnd 1 2 a b comparator comparator op-amp buffer 50 m buffer 50 m guard 0.57 v ( ) 10 pin gnd r 1.7 v (1.7 v) e 1.4 v (1.2 v) f 1.1 v (0.7 v) guard diff&lpf 10 7 khz
