Block Diagram
TA6038FN detects an existence of external shock through the
TA6038FN 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.
TA6038FN incorporates 1-ch shock detecting circuitry.
Input terminal of sensor signal is designed high impedance.
LPF (low pass filter) circuitry is incorporated.
Sensitivity of shock detection can be adjusted by external devices.
Small package
Differential input impedance = 100 MΩ (typ.)
Cut-off frequency of LPF = 7 kHz
