TPS2231PWG4

The TPS2231PWG4 ExpressCard power interface switches provide the total power management solutiorequired by the ExpressCard specification. The TPS2231 and TPS2236 ExpressCard power interface switche distribute 3.3 V, AUX, and 1.5 V to the ExpressCard socket. Each voltage rail is protected with integrate current-limiting circuitry. The features of the TPS2231PWG4 are: (1)Meets the ExpressCard(TM) Standard; (2)Compliant with the ExpressCard(TM); (3)Compliance Checklists; (4)Fully Satisfies the ExpressCard(TM); (5)Implementation Guidelines; (6)Supports Systems with WAKE Function; (7)TTL-Logic Compatible Inputs; (8)Short Circuit and Thermal Protection; (9)40°C to 85°C Ambient Operating; (10)Temperature Range.

The following is about the absolute maximum ratings of TPS2231PWG4: (1)input voltage range for card power: -0.3 to 6V; (2)output voltage range:  -0.3 to 6V; (3)output current: internal limited; (4)operating virtual junction temperature range: -40 to 120; (5)storage temperature range: -55 to 150; (6)lead temperature 1,6mm from case 10 seconds: 260.

The electrical characteristics of the TPS2231PWG4 are: (1)power switch resistance: 45m at TJ=25, I=1300mA each; (2)short-circuit output current: 1.35A min, 2A typical and 2.5A max; (3)thermal shutdown: 155 min and 165 typical at rising temperature, not in overcurrent condition; (4)current-limit reponse time: 43s typical and 100s max; (5)operation input quiescent current: 125A typical and 200A max.
