The MAX4896 8-channel relay and load driver is designed for medium voltage applications up to 50V. This device is offered in a 20-pin, 5mm x 5mm TQFN package, resulting in substantial board space savings.The MAX4896 8-channel relay driver offers built-in inductive kickback protection, drive for latching/nonlatching or dual-coil relays, and open-load and short-circuit fault detection.The MAX4896 also protects against overcurrent conditions. Each independent open-drain output features a 3Ω (typ) on-resistance, and is guaranteed to sink 200mA of load current (VS≥ 4.5V).A built-in overvoltage protection clamp handles kick-back-voltage transients, which are common when driving inductive loads. Thermal-shutdown circuitry shuts off all outputs (OUT_) when the junction temperature exceeds +160°C. The MAX4896 employs a reset input that allows the user to turn off all outputs simultaneously with a single control line.The MAX4896 includes a 10MHz SPI™-/QSPI™-/MICROWIRE™-compatible serial interface. The serial interface is compatible with TTL-/CMOS-logic voltage levels and operates with a single +2.7V to +5.5V supply. In addition, the SPI output data can be used for diagnostics purposes including open-load and short-circuit fault detection.The MAX4896 is offered in the extended (-40°C to +85°C) and (-40°C to +125°C) operating temperature ranges.ApplicationsATE SystemsIndustrial EquipmentPower-Grid Monitoring and Protection EquipmentWhite Goods

The MAX481E, MAX483E, MAX485E, MAX487E- MAX491E, and MAX1487E are low-power transceivers for RS-485 and RS-422 communications in harsh environments. Each driver output and receiver input is protected against ±15kV electro-static discharge (ESD) shocks, without latchup. These parts contain one driver and one receiver. The MAX483E, MAX487E, MAX488E, and MAX489E feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps. The driver slew rates of the MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E are not limited, allowing them to transmit up to 2.5Mbps.These transceivers draw as little as 120µA supply current when unloaded or when fully loaded with disabled drivers (see Selector Guide). Additionally, the MAX481E, MAX483E, and MAX487E have a low-current shutdown mode in which they consume only 0.5µA. All parts operate from a single +5V supply.Drivers are short-circuit current limited, and are protected against excessive power dissipation by thermal shutdown circuitry that places their outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.The MAX487E and MAX1487E feature quarter-unit-load receiver input impedance, allowing up to 128 transceivers on the bus. The MAX488E-MAX491E are designed for full-duplex communications, while the MAX481E, MAX483E, MAX485E, MAX487E, and MAX1487E are designed for half-duplex applications.

The MAX4901–MAX4905 switches feature negative signal capability that allows signals below ground to pass through without distortion. The MAX4901/MAX4902 are a dual SPST (single-pole/single-throw) and the MAX4903/MAX4904/MAX4905 are a single SPDT (single-pole/double-throw) configuration. These analog switches operate from a single +1.8V to +5.5V supply and have low 0.6Ω on-resistance, making them ideal for switching audio signals.The MAX4905 includes a comparator that can be used for headphone detection or mute/send key function. The MAX4902/MAX4904/MAX4905 have internal shunt resistors to automatically discharge any capacitance at the NO_ and NC connection points. This reduces click-and-pop sounds that occur when switching audio signals between pre-charged points. A break-before-make feature and auto-discharge also help to reduce popping.These SPST and SPDT switches are available in space-saving 8-pin TDFN and 9-bump UCSP™ packages and operate over the -40°C to +85°C extended temperature range.ApplicationsCell PhonesMP3 PlayersNotebook ComputersPDAs and Handheld Devices
