MAX4520EUT+T

The MAX4520EUT+T is a rail to rail, fault protected, SPST analogue switch in 6 pin SOT-23 package. The terminals are protected from overvoltage faults up to 36V during power-on and 44V with power off. During a fault condition, the switch input terminal becomes an open circuit only nano amperes of leakage current flow from the fault source and the switch output (COM) furnishes up to 13mA of the appropriate polarity supply voltage to the load. This ensures unambiguous rail to rail outputs when a fault begins and ends. On-resistance is 160 ohm max. The off leakage current is only 0.5nA at +25°C and 10nA at +85°C. The digital input has +0.8V and +2.4V logic thresholds ensuring both TTL and CMOS logic compatibility when using ±15V or a single +12V supply.

• Supply voltage range is 9V to 36V, ±4.5V to ±20V
• Operating temperature range from -40°C to 85°C
• Normally open switch
• ±40V fault protection with power off and ±36V fault protection with ±15V supplies
• Switch is off with power removed
• On switch turns off with overvoltage
• Output clamped to appropriate supply voltage during fault condition with no transition glitch
• No power supply sequencing required
• Low power consumption of less than 2mW
