Each device is a dual-channel load switch with controlled turnon. The device contains two N-channel MOSFETs that can operate over an input voltage range of 0.6 V to 5.7 V, and can support a maximum continuous current of 6 A per channel. Each switch is independently controlled by an on and off input (ON1 and ON2), which can interface directly with lowvoltage control signals. The TPS22976 is capable of thermal shutdown when the junction temperature is above the threshold, turning the switch off. The switch turns on again when the junction temperature stabilizes to a safe range. The TPS22976 also offers an optional integrated 230-Ω on-chip load resistor for quick output discharge when the switch is turned off. • • • • • • • • • • Integrated dual-channel load switch Input voltage range: 0.6 V to VBIAS VBIAS voltage range: 2.5 V to 5.7 V On-resistance – RON = 14 mΩ (typical) at VIN = 0.6 V to 5 V, VBIAS = 5 V – RON = 18 mΩ (typical) at VIN = 0.6 V to 2.5 V, VBIAS = 2.5 V 6-A maximum continuous switch current per channel Quiescent current for TPS22976, TPS22976N – 37 µA (typical, both channels) at VIN = VBIAS = 5 V – 35 µA (typical, single channel) at VIN = VBIAS = 5 V Quiescent current for TPS22976A – 85 µA (typical, both channels) at VIN = VBIAS = 5 V – 83 µA (typical, single channel) at VIN = VBIAS = 5 V Control input threshold enables use of 1.2-, 1.8-, 2.5-, and 3.3-V logic Configurable rise time Fast turn ON time (TPS22976A) – tON = 17µs at VIN = 1.05V Thermal shutdown Quick Output Discharge (QOD) (optional) SON 14-pin package with thermal pad ESD performance tested per JESD 22 – 2-kV HBM and 1-kV CDM 2 Applications • • • • • • Ultrabook™ Notebooks and Netbooks Tablet PCs Set-top Boxes and Residential Gateways Telecom Systems Solid-State Drives (SSD) The TPS22976 is available in a small, space-saving 3-mm × 2-mm 14-SON package (DPU) with integrated thermal pad allowing for high power dissipation. The device is characterized for operation over the free-air temperature range of –40°C to 105°C.
