HA16688MP

The HA16688MP is a low-noise,8-channel read/write circuit developed for use with small hard disk drives.The HA16688MP has 4 functions.The first one is read amplifier.The second one is write driver.The third one is write fault detector.The fourth one is fixed write current select.

The HA16688MP has 9 features.The first one is two-power supply design (+5V and +12V).The second one is easily extendable for systems with more than 8 channels.The third one is low noise read amplifier has differential gain of 200(typ).The fourth one is emitter-follower fixed current read amplifier output.The fifth one is write current can be selected by an extemal resistor.The sixth one is built-in power supply monitor for both 5 V and 12 V prevents incorrect writes.The seventh one is TTL-compatible interface.The eighth one is compact surface-mount package.The ninth one is symmetrical arrangement of head input/output and controller signal/pins.

The HA16688MP has some information about absolute maximum ratings (Ta = 25).When the parameter is digital power supply,the symbol is V5,the rating is 6.0,the unit is V,the pins is V5.When paraeter is analog power supply,the symbol is V12,the rating is 14.0,the unit is V,the pins is V12.When paraeter is write current,the symbol is IW,the rating is 60,the unit is mA.When paraeter is input voltage ,the symbol is Vin,the rating is -0.3 to V5 +0.3,the unit is V,the pins is HS0,HS1,HS2,WDi,R/W,CD.When paraeter is WUS voltage,the symbol is WUS,the rating is 14.0,the unit is V,the pins is VWUS.When paraeter is WUS output current,the symbol is IWUS,the rating is 12,the unit is mA,the pins is WUS.When paraeter is center tap output current,the symbol is ICD,the rating is -60,the unit is mA,the pins is VCT.When paraeter is read data output current,the symbol is Iro,the rating is -10,the unit is mA,the pins is RDX,RDY.
