使能端高电平有效、具有电流限制和消隐功能的 5.5V、0.1A、500mΩ 负载开关

The TPS22941/2/3/4/5 load switches provide protection to systems and loads in high-current conditions. The devices contain a 0.4-Ω current-limited P-channel MOSFET that can operate over an input voltage range of 1.62 V to 5.5 V. Current is prevented from flowing when the MOSFET is off. The switch is • Input Voltage Range: 1.62 V to 5.5 V\n• Low ON resistance \n• rON = 0.4 Ω at VIN = 5.5 V\n• rON = 0.5 Ω at VIN = 3.3 V\n• rON = 0.6 Ω at VIN = 2.5 V\n• rON = 0.8 Ω at VIN = 1.8 V\n \n• Minimum Current Limit: 40 mA or 100 mA\n• Undervoltage Lockout (UVLO)\n• Thermal Shutdown\n• Shutdown Current (A1;
