TA8564FN

The TA8564FN is a kind of shock sensor IC (2ch version) which detects an existance of external shock through the shock sensor and outputs.

There are some features of the TA8564FN as follows: (1)the device operates from 5 VDC single power supply voltage; (2)the signal from shock sensor is amplified according to the setting gain, and is detected through the internal window comparator; (3)the device incorporates 2-ch shock detecting circuitry; (4)input terminal of sensor signal is hi-impedance: input impedance=50 M typ; (5)LPF (low pass filter) circuitry is built in: cut off frequency of LPF=7 kHz; (6)sensitivity of shock detection can be adjusted by external devices; (7)the device can output the differential signal between two sensors; (8)the device is designed for low power dissipation: active mode (pin 10: 5 V): 3 mA typ; powersave mode (pin 10: 0 V): 0.1A typ; (9)small package: SSOP16-P-225-0.65B (0.65 mm pitch).

The following is about the maximum ratings of the TA8564FN: (1)power supply voltage, VCC: 7 V; (2)input voltage to PS terminal, VIN: -0.3 to VCC+0.3 V; (3)power dissipation, PD: 560 mW; (4)storage temperature, Tstg: -55 to 150. Then is about the recommended operating condition: (1)power supply voltage, VCC: 4.2 to 5.5 V; (2)operating temperature, TOPR: -25 to 85.

The last one is about the electrical characteristics (unless otherwise specified. VCC=5 V, Ta=25) of the TA8564FN: (1)supply current (in active mode), ICCD: 3 mA typ and 3.6 mA max at Pin 10 (PS)=5 V; (2)supply current (in PS mode), ICCS: 0.1 A typ and 1.0 A max at Pin 10 (PS)=0 V; (3)input impedance, ZIN: 50 M typ at input impedance of pin1 (SIX), 16 (SIY); (4)LPF cut-off frequecy, fc: 5 kHz min, 7 kHz typ and 10 kHz max at -3 dB; (5)OP-AMP input current, IIN: 30 nA typ and 100 nA max; (6)OP-AMP fT: 1.5 MHz typ.
