TB6078FUG
TOSHIBA Bi-CMOS Linear Integrated Circuit
Silicon Monolithic
TB6078FUG
Shock Sensor IC
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.
Features
SSOP8-P-0.65
•
•
•
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)
Weight: 0.02 g (typ.)
It is possible to adjust frequency characteristic and gain by changing external devices

Note: The absolute maximum ratings of a semiconductor device are a set of ratings that must not be exceeded, even
for a moment. Do not exceed any of these ratings.
Exceeding the rating(s) may cause device breakdown, damage or deterioration, and may result injury by
explosion or combustion.
