IMP Manuals

The document describes the features and characteristics of IMP5111/5112 SCSI terminators. They have ultra-fast response for fast-20 SCSI applications, 35MHz channel bandwidth, 3.3V operation, less than 3pF output capacitance, sleep-mode current less than 275µA, thermally self-limiting, no external compensation capacitors required, support 8-bit or 16-bit (wide) applications, compatible with active negation drivers (60mA / channel), compatible with passive and active terminations, approved for use with SCSI 1, 2, 3 and Ultra SCSI, hot swap compatible, pin-for-pin compatible with LX5211 and UC5606 (IMP5111), and pin-for-pin compatible with LX5212 and UC5603/5613/5614 (IMP5112).

The document introduces the LDOs POWER MANAGEMENT product series, including IMP3, IMP37, IMP20, IMP20114/15, IMP25, IMP21185, IMP205, IMP2054/55, IMP24/55, IMP21186, IMP2070/711, IMP2, and IMP211887. These products have features such as low dropout, adjustable output, super low dropout, CMOS technology, battery life extending shutdown mode, and ERROR output.

The IMP5245/5246 is a Low Voltage Differential (LVD) terminator designed to comply with the LVD termination specification in the SPI-2 document. It is designed specifically for LVD applications. It supports 9 channels and eliminates external VREF capacitors, so it has a lower output capacitance than multimode terminators. The IMP5245/5246 delivers the ultimate in SCSI bus performance while saving component cost and board area.

The IMP525 is an Electroluminescent (EL) lamp driver designed for systems that must operate below 1 volt. It is suitable for products such as audio/TV remote control units, pagers/cellular phones, PDAs, clocks and radios, portable GPS receivers, LCD modules, and toys.

The document introduces the features and characteristics of the IMP811/IMP812 low-power power supply monitors, including the power supply voltage range, monitored power supply voltage, reset signal, reset pulse width, reset input, etc.

The IMP5121 is a high performance SCSI terminator which features a low voltage BiCMOS architecture that provides performance superior to older passive and active techniques. The IMP5121 has a 35MHz channel bandwidth and each channel employs high performance adaptive elements to provide the fastest possible response time. The IMP5121 also eliminates the output compensation capacitor required in earlier terminator designs.
