SL7050AQ

SL70xxA Low Power Voltage Detector General Description The SL70XXA series devices are a set of three terminal low power voltage detectors implemented in CMOS technology. Each voltage detector in the series detects a particular fixed voltage ranging from 2.2V to 7.0V. The voltage detectors consist of a highprecision and low power consumption standard voltage source as well as a comparator, hysteresis circuit, and an output driver. CMOS technology ensures low power consumption. Although designed primarily as fixed voltage detectors, these devices can be used with external components to detect user specified threshold voltages . Features ● Low power consumption ● Low temperature coefficient ● Built-in hysteresis characteristic ● High input voltage (up to 15V) ● Output voltage accuracy: tolerance ±1% or ±2% ● TO92, SOT89 ,SOT23 and SOT23-3 package Applications ● ● ● ● ● ● Battery checkers Level selectors Power failure detectors Microcomputer reset Battery memory backup Non-volatile RAM signal storage protectors www.slkormicro.com 1 SL70xxA Order Information Part No SL7022A SL7024A SL7044A SL7050A SL7070A Package TO92 SOT89 SOT23-3 SOT23 SL70 Detectable Voltage Hysteresis Width Tolerance 2.2V 2.4V 4.4V 5.0V 7.0V 0.11V 0.12V 0.22V 0.25V 0.35V ±2% ±2% ±2% ±2% ±2% Manner of Packing Bag 1000PCS/bag Reel 1000PCS/reel Reel 3000PCS/reel Reel 3000PCS/reel Package Type A:SOT-23 C:SOT-23-3 Q:SOT-89 E:TO-92 A Detectable Voltage 22 : 2.2V 24 : 2.4V 44 : 4.4V 50 : 5.0V 70 : 7.0V www.slkormicro.com Devices per bag/reel 2 SL70xxA Block Diagram and Pin Arrangement Diagram Pin Assignment Pin No. Pin Name 1 VOUT 2 VIN Supply Voltage Input. 3 GND Ground connection. www.slkormicro.com Description Output. 3 SL70xxA Output Table & Curve V DD V OUT V DD ≤V DET (-) V SS V DD >V DET (+) Hi-Z Functional Description The SL70XXA series devices are a set of three terminal low power voltage detectors implemented in CMOS technology.
