Product Summary
The CXA1362Q is a read/write amplifier for floppy disk drive with built-in filer. The CXA1362Q is designed for FDD ( floppy disk drive) use. The CXA1362Q combines such functions as Readm Writem Erase and Supply voltage detection circuits in a single chip.
Parametrics
CXA1362Q absolute maximum ratings: (1) supply voltage Vcc: 7V;(2) Digital signal input pin input voltage: -0.5 to Vcc +0.3V; (3) Power on output voltage applied: Vcc +0.3V; (4) Erase output voltage applied: Vcc +0.3V; (5) Head 0A, 1A, and 1B voltage applied: 15V; (6) Power on output sink current: 7mA; (7) erase output sink current: 150mA; (8) operating temperature Topr: -20 to +75°C; (9) storage temperature: -65 to +150°C; (10) allowable power dissipation: 500mW.
Features
CXA1362Q features: (1) 5V single power supply operation; (2) built-in filter permits switching to 4 modes 1M/2M, inner and outer tracks; (3) filter characteristics can be customized; (4) preamplifier input equivalent noise voltage; (5) built-in function to select the pulse width of the 1st monostable multivibrator in the time domain filter enables selection through 1M/2M mode; (6) built-in write current selection function allows for 4 mode write current selections: 1/2M, inner and outer tracks (other than the filter inner/puter track) ; (7) built-in supply voltage detction circuit prohibits irregular write during power supply rise, fall or abnormal voltage; (8) power consumption is kept to low 120mW (TYP. ) making suitable for battery drive FDD.
