TPS3779/80: Dual Channel, Low Power Voltage Detector in small 1.5x1mm package Features Benefits • Two independent channels in Small (1.45mm X 1mm) µSON package • Low Quiescent Current : 2.2uA (typ) • High Accuracy on Threshold and Hysteresis: 1.0% ( -40C to 125C) • Multiple (falling) hysteresis options • 0.5%, 1%, 5%, 10% • Push-Pull(TPS3779)/Open Drain(TPS3780) output options • Available in Small SON or SOT23-6 package • Less board area - Good for space critical designs • Power Sensitive Applications • Accurate power good/ fail output • Choose based on system tolerance • Different output choices for system flexibility, no external pull up for push-pull, wire-or with open drain Applications • • • • • • • Portable Medical Devices Building Automation (Smoke Detectors) Storage and Servers Notebook/Desktop Computers Set-Top Boxes DSPs, ucontrollers or uprocessors Other Portable/Battery-Powered Applns Device VIN VSENSE Hysteresis IDD Package TPS3779/80 1.5V – 6.5V Adj (>1.2V) Multiple 2.2uA SON-6 1 SOT23-6 Portfolio Positioning Specification TPS3780 TPS3805 TPS3803 Dual Channelno delay Dual Channelno delay Single Channel- Single ChannelSingle Channel- Single ChannelQuad Channel no delay no delay no delay delay delay Channel 2 2 1 1 4 1 1 Temp Range -40 to +125C -40 to +85C -40 to +85C -40 to +85C -40 to +125C -40 to +125C -40 to +85C 1.5V to 6.5V 1.5V to 6.0V 1.5V to 6.0V 1.0 to 6.0V 1.8V to 6.5V 1.7V to 6.5V 0.9 to 6.5V 4uA max 6uA 4uA 1.4uA @25C 19uA 10uA 0.5 1.00% 1.50% 1.50% 2.5% @25C 1% 1% 2.50% 1 X 1.5mm µSON, SOT23-5 SC70 SC70 SOT23 4x4mm 1x 1.5mm uSON 1x1mm SON <10us <10us <10us 60us 20ms 40us 200ms Adjustable PP/OD 3.3V fixed / Adj Adjustable Push Pull Open Drain Fixed: 2.0V Open Drain Adjustable Open Drain Adjustable PP/OD Fixed Push Pull Mult(0.5% to 10%) 1% 5% 1% 1% 1% Vcc Voltage Range Quiescent Current (max @85C) Accuracy (over temp) Package Reset Time ( L>H) LM8364 TPS386000 TPS3895 TPS3839 Thresholds Output Hysteresis options 1% 2 Competitive Analysis Specification Channel TPS3780 2 MAX6780 2 Temp Range -40 to +125C -40 to +85C Vcc Voltage Range 1.5V to 6.5V 1.6V to 5.5V 2.5 to 5.5V 2.5 to 5.5V 0.5V to 6V Quiescent Current (max @85C) 4uA max 7uA max 16uA max 30uA max 1.6uA max 1.00% 1.00% Accuracy (over temp) Package Reset Time Thresholds Output 1 X 1.5mm SON, SOT23-5 <10us ADM6305 MIC2772 2 -40 to +125C 2.50% R3114 2 1 -40 to +85C -40 to +85C 2.50% 1.50% 1 X1.5mm SON SOT23-5 2x2 SON 1x1mm SON mutiple (1ms to <10us 1s) 20ms/140ms <50us Adjustable Adjustable PP/OD PP/OD Hysteresis options Multiple (0.5% to Multiple (0.5% to 10%) 10%) Adjustable OD Fixed multiple Fixed multiple OD PP/OD 3 Where we won: TPS3780 High Accuracy, Dual Channel Voltage Detector Application SSD • Need to monitor multiple voltages in a system, TPS3780 provides a small 1.5 x1mm package for two channels • Low Iq consumption for portable applications • High Accuracy for positive and negative going threshold to provide accurate voltage monitoring in case of unplanned power down. Why the customer preferred TI • High accuracy for positive and negative threshold : 1% over -40C to 125C • Business Results Better than two one channel ICs or discrete solution of compatator + reference IC. • Multiple hysteresis options for different applications: 0.5%, 1%, 5%,10% • Low Iq : 2.2uA , Small package 1 x1.5mm TI Confidential – NDA Restrictions 4 4 • SSD opportunities • STB opportunities
