Description

The TPS2097DR is one member of the TPS2097 series.The TPS2097 quad power-distribution switche is intended for applications where heavy capacitive loads and short circuits are likely to be encountered.The TPS209x devices incorporate 80-m N-channel MOSFET high-side power switches for power-distribution systems that require multiple power switches in a single package. Each switch is controlled by an independent logic enable input. Gate drive is provided by an internal charge pump designed to control the power-switch rise times and fall times to minimize current surges during switching. The charge pump requires no external components and allows operation from supplies as low as 2.7 V.

Features of the TPS2097DR are:(1)80-m high-side MOSFET switch; (2)250 mA continuous current per channel; (3)independent thermal and short-circuit protection with overcurrent logic output; (4)operating range:2.7-V to 5.5-V; (5)CMOS- and TTL-compatible enable inputs; (6)2.5-ms typical rise time; (7)undervoltage lockout; (8)10 A maximum standby supply current; (9)bidirectional switch; (10)available in 8-Pin and 16-Pin SOIC packages; (11)ESD protection.

The absolute maximum ratings of the TPS2097DR can be summarized as:(1)input voltage range:0.3 V to 6 V;(2)output voltage range:0.3 V to Vi(in)+ 0.3 V;(3)storage temperature:-65 to 150;(4)lead temperature (soldering 5s):260;(5)operating virtual junction temperature range:0to 125.Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.A sense FET monitors the current supplied to the load. The sense FET measures current more efficiently than conventional resistance methods. When an overload or short circuit is encountered, the current-sense circuitry sends a control signal to the driver. The TPS2097DR driver in turn reduces the gate voltage and drives the power FET into its saturation region, which switches the output into a constant current mode and holds the current constant while varying the voltage on the load.
