The 53272 is a single channel power MOSFET optocoupler expanding upon the electrical performance of Mii P/N 53124 with reduced RDS(ON) and increased current capability.
Performance is specified over the full military temperature range. Functionally, the device operates as a single-pole, normally open (1 Form A) solid-state relay. The device is actuated by an input current, which can be supplied from standard logic types such as open-collector TTL. The input current biases a light emitting diode that is optically coupled to an integrated photovoltaic diode array. The photovoltaic array powers control circuitry that operates the output MOSFETs. Optimum switching of either AC or DC loads is provided by a configurable output. For AC loads, Connection A in Figure 1 must be used. Connection A will also switch DC loads but Connection B, in Figure 1, provides DC-only operation with the advantages of substantial reduction in on-resistance and twice the output current capability as that obtained with Connection A.
