The MAX4821EUP+T is an 8-channel relay driver IC manufactured by Analog Devices (formerly Maxim Integrated). This device is designed to drive +3.3V and +5V non-latching or dual-coil-latching relays, making it particularly useful for applications involving +3V relays. Each of the eight independent open-drain outputs is capable of sinking a minimum of 70mA load current and features a typical 2 Ohm on-resistance.
The MAX4821EUP+T supports both parallel and serial interfaces, allowing for flexible integration into various system designs. It includes separate set and reset functions for simultaneous control of all outputs. The device operates over a temperature range of -40°C to 85°C (TA) and is housed in a space-saving 20-pin TSSOP-EP package, suitable for surface mounting.
Key electrical characteristics include a load voltage range of 2.3V to 5.5V and a low quiescent supply current of less than 50µA. The built-in hysteresis on digital inputs accommodates slow-rising and falling signals, enhancing reliability in noisy environments. Applications for this relay driver include central office equipment, ATE systems, DSL/ADSL line cards, industrial equipment, and E1/T1 redundancy.
