Shock Sensor IC
Features
Block Diagram
TB6078FUG detects “ shock” through the external shock sensor
and output Low-level signal at 7 pin.
It has so excellent characteristic in low noise, and is suitable for
application of mechanical control systems of HDD.
Single power supply: 2.7 V to 5.5 V single power supply operation
Two Operatinal-Amplifier is built in for design flexibility.
Super small package: SSOP8-P-0.65 (0.65 mm pitch)
It is possible to adjust frequency characteristic and gain by changing external devices
Note: Some of the functional blocks, circuits, or constants in the block diagram may be omitted or simplified for
explanatory purpose.
