The switch is controlled by a high input • Input Voltage Range: 1.4-V to 5.5-V (ON), which is capable of interfacing directly with low- voltage control signals. • Low ON-Resistance The slew rate of the device is internally controlled in – rON = 60-mΩ at VIN = 5-V order to avoid inrush current. The TPS22912 family – rON = 61-mΩ at VIN = 3.3-V has various rise time options and is active high – rON = 74-mΩ at VIN = 1.8-V enable. (see Table 1). – rON = 84-mΩ at VIN = 1.5-V The TPS22912 provides circuit breaker functionality • 2-A Maximum Continuous Switch Current by latching off the power switch during reverse voltage situations. An internal reverse voltage • Low Threshold Control Input comparator disables the power switch when the • Controlled Slew-rate Options output voltage (VOUT) is higher than the input (VIN). • Under-Voltage Lock Out This process quickly (10µs typical) stops the flow of • Reverse Current Protection current towards the input side of the switch. Reverse current protection is always active, even when the device is disabled. Additionally, under-voltage lockout APPLICATIONS (UVLO) protection turns the switch off if the input • Portable Industrial / Medical Equipment voltage is too low. • Portable Media Players The TPS22912 is available in a ultra-small, space- • Point of Sales Terminals saving 4-pin CSP package and is characterized for • GPS Navigation Devices operation over the free-air temperature range of –40°C to 85°C. • Digital Cameras • Portable Instrumentation TYPICAL APPLICATION • Smartphones / Wireless Handsets Table 1.
