Product Summary
The LTC1531CSW is an isolated self-powered dual differential comparator. An internal capacitive isolation barrier provides 2500V of isolation between the comparator and its output. The part provides UL-rated isolated comparisons without the need for an isolated supply since both comparator power and output data are transmitted across the capacitive barrier. Applications are (1)Self-powered isolated sensing; (2)Isolated temperature control; (3)Isolated voltage monitor; (4)Isolated switch control.
Parametrics
LTC1531CSW absolute maximum ratings: (1)Total Supply Voltage (VCC to GND): 7V; (2)Input Voltages Isolated Comparator (V1 to V4): – 0.3V to (VPW + 0.3V)Current; (3)Input Pins: ±10mA; (4)Operating Temperature Range: 0°C to 70°C; (5)Storage Temperature Range: –65°C to 150°C; (6)Lead Temperature (Soldering, 10 sec): 300°C.
Features
LTC1531CSW features: (1)UL Recognized File E151738 to UL1577; (2)Self-Powered Across IsolatioBarrier; (3)2500VRMS Isolation; (4)2.5V Isolated Reference, ILOAD = 5mA; (5)Zero-Cross Output for Line Power; (6)Dual Differential Input Comparator; (7)High Input Impedance Comparator.
