11 / 16 page Miniature, Two-Wire, True Zero Speed Differential Peak-Detecting Sensor IC ATS682LSH 11 Allegro MicroSystems, Inc. 115 Northeast Cutoff Worcester, Massachusetts 01615-0036 U.S.A. 1.508.853.5000; www.allegromicro.com Power Supply Protection The device contains an on-chip regulator and can operate over a wide VCC range. For devices that need to operate from an unregu- lated power supply, transient protection must be added externally. For applications using a regulated line, EMI/RFI protection may still be required. Contact Allegro for information on the circuitry needed for compliance with various EMC specifications. Refer to figure 7 for an example of a basic application circuit. Undervoltage Lockout When the supply voltage falls below the undervoltage lockout threshold, VCC(UV), the device enters Reset mode, where the output state returns to the Power-On State (POS) until sufficient VCC is supplied. ICC levels may not meet datasheet limits when VCC < VCC(min). Assembly Description This device is molded into a plastic body that has been optimized for size, ease of assembly, and manufacturability. High operat- ing temperature materials are used in all aspects of construction. Refer to the Allegro website, www.allegromicro.com, for more specific applications notes on finished package processing. Diagnostics The regulated current output is configured for two-wire applica- tions, requiring one less wire for operation than do switches with the traditional open-collector output. Additionally, the system designer inherently gains diagnostics because there is always output current flowing, which should be in either of two nar- row ranges, shown in figure 8 as ICC(HIGH) and ICC(LOW). Any current level not within these ranges indicates a fault condition. If ICC > ICC(HIGH)(max), then a short condition exists, and if ICC < ICC(LOW)(min), then an open condition exists. Any value of ICC between the allowed ranges for ICC(HIGH) and ICC(LOW) indicates a general fault condition.
