All 85-0322 assemblies require a sticker to be applied post-construction. This sticker shall be applied by whomever constructs the boards. This sticker shall be as such: # 1 2 3 4 5 85-0322-010 85-0322-011 85-0322-012 85-0322-013 85-0322-014 Allegro Part: ACS712ELC-05B-T ACS712ELC-20A-T ACS712ELC-30A-T ACS713ELC-20A-T ACS713ELC-30A-T Label ASEK712ELC-05B-T ASEK712ELC-20A-T ASEK712ELC-30A-T ASEK713ELC-20A-T ASEK713ELC-30A-T 2. This sticker may be applied onto the top of the board, if it can be. If the sticker is topside, it shall be located between U1 and the silkscreen text "Current Sensor". This is if it will fit, without overlaying any silkscreen text or solderpads. If the sticker is larger than that area, the sticker shall be located on the backside of the PCB. 3. Any sticker applied by the assembly house (not of the type above) shall be installed on the backside of the pcb. [This may be a tracking number, or the assembly house P/N.] The label shall not cover any holes used for soldering. 4. The Allegro sensor may be installed at any time. That is, all the parts required to build an 85-0322-010 (for example) may be installed at the same time. 5. RJ: 22g jumper. Use 22g buss wire, 0.5 inch body, with 0.25 inch leads bent 90 degree. Install 0.125 inch above PCB (not critical). Solder and trim. This component will be used for scope ground clips. 0.5" LS 0.25" leads Intial bending: 0.125" above PCB 6. It is recommended that the SMT parts be installed first, then thro-hole, then banana jacks and standoffs, lastly the sticker(s). Any order of operations may be performed, however. ACS7xx Demo Board 85-0322-000-NTS Originator: Shawn Upton Construction Notes Page 1 of 1 Rev 2 9/21/2006 All components and assembly practices must be RoHS Compliant Certificates of RoHS compliance must be sent to Allegro for record keeping To Install RJ: use buss wire, approx 22-24g. Bend a 1 inch length to 0.5 inch lead spacing, just like as if forming leads for a conventional resistor. Install approximately 0.25 inch above the PCB. This jumper is scope ground clips and must have ample space under it! 85-0322 Rev A.xls 1 2 3 4 IPA A U1 1 2 3 4 IP+ IP+ IP+ IPIP- VCC VIout N/C GND 8 7 6 5 R1 zero ohm C5 DNI AGND ACS7xx Vout CF C4 DNI TP5 AGND AGND +Vin B U2 AGND C1 10uF 1 2 3 Vin GND On/OFF +5.0 Vout 5 B C2 10uF LP2980AIM5-5 C3 0.1uF AGND AGND AGND TP1 J1 L1 +5.0 INDUCTOR +Vin 1 2 3 4 5 6 AGND Vout CF +Vin TP2 +5.0 TP3 AGND TP4 Molex 22-11-2061 Vout RJ C AGND JB1 C AGND zero ohm IP+ H1 0 BANANA JACK JB2 4-40 MOUNTING HOLE H2 IP- 0 4-40 MOUNTING HOLE H3 BANANA JACK JB3 0 4-40 MOUNTING HOLE H4 GND 0 D BANANA JACK JB4 RoHS/Pb-free Label 4-40 MOUNTING HOLE GND BANANA JACK Title Logo ACS7xx Demo Board Allegro MicroSystems, Inc 955 Perimeter Rd Manchester NH 03103 Date: 9/21/2006 Time: 2:29:13 PM Sheet 1 of 1 File: C:\Documents and Settings\supton\My Documents\DXP\85-0322\85-0322 Rev 2.SchDoc Allegro Logo Size: ALLEGRO LOGO 1 TP1 - TP4: Testpoints for 0.063 hole: Keystone Electronics 5005 or equivalent JB1 - JB4: use Johnson Components 111-2223-001 Banana jack C1, C2: 1206 16V 10uF: Panasonice ECJ-HVB1C106M C3: 0603 16V 0.1uF: Panasonic ECJ-1VB1C104K L1: 0603 Murata BLM18BB471SN1D R1: 0603 zero ohm: Panasonic ERJ-3GEY0R00V RJ: Use buss wire, 0.5inch long and 0.25inch above PCB 2 A Number: 85-0322-000-SCH 3 Revision: 2 4 D ACS7xx Demo Board 85-0322-001-BOM Originator: Shawn Upton ITEM QTY S Bill of Materials Page 1 of 3 P/N Manufacturer Rev 3 5/28/2008 DESCRIPTION REF 1 2 3 2 1 6 6 Panasonic Panasonic ECJ-HVB1C106M ECJ-1VB1C104K capacitor, monolythic, 1206, X5R, 10uF, 16V capacitor, monolythic, 0603, X5R, 0.1uF, 16V Do Not Install C1, C2 C3 C4, C5 4 1 6 Panasonic ERJ-3GEY0R00V resistor, metal film, 0603, 5%, zero ohm R1 5 1 6 Murata BLM18BB471SN1D inductor, 0603 L1 6 1 10 National Semi LP2980AIM5-5.0 IC, voltage regulator, 5V, SOT-23-5 U2 7 8 9 10 4 5 4 4 10 10 Johnson Components 111-2223-001 Keystone Electronics 5005K 6 Keystone Electronics 1450C IP+, IP-, IPGND, IPGND TP1 through TP5 see construction notes see construction notes 11 12 1 1 10 Molex 22-11-2062 13 1 10 connector, banana plug testpoint, 0.063 inch diameter, red screw, zinc metal plated, 4-40, 0.5 inch, Philips standoff, male/male, zinc metal plated, 4-40, 0.5 inch long, hex shaped connector, friction lock header, 6 pin buss wire, tinned, 22 or 24 gauge 0.5 inch long.

When questions arise to a component parameter/designation/etc, please refer to line item number first when inquiring. QTY: the quantity of items to be ordered per finished assembly. Note: higher level documents may call this BOM multiple times S: BOM Substitution Instructions. See below Manufacturer: Recommended (or required) Manufacturer for the part(s). Note: multiple manufacturers may be listed per line item. Note: if no manufacturer part number is given, the the item is considered generic enough that that any manufacturer should work. Ie, 1N4001 in a DO-41 P/N: The manufacturers part number. Note: if multiple manufacturers are listed, this P/N will correspond only to the manufacturer to the immediate left of the P/N Note: Manufacturer part number may be incomplete; if not enough information is given, see below. Description: this is a generic description of the part. Package size, part type, minimum/maximum requirements are listed. Note: this is generic and may not exactly reflect the suggested/required part. For example, "capacitor, 25V" while the manufacturer P/N is actually 50V. The capacitor is required to a minimum of 25V rated (important only if second sourcing) Ref: This is the list of component designators. If "see construction notes" is listed, the construction notes must be used to determine component location (not marked on board etc) Note: surface mount components may have a designator listed but not marked on PCB silkscreen; if so then refer to -CPG (or similar) drawing for location and/or the pick and place file (as found in the gerber files) If a line item has multiple part numbers, they are not to be interpreted as any order of preference If a line item has multiple part numbers, and the substitution code is 10, then only use parts as listed. Mixing is allowed (for example, if 2 manufacturers are listed, and qty is 5, then 2 parts may be from vendor A and 3 parts from vendor B) regardless of code. BOM Substitution Notes: The third column nomenclature is to be used for second sourcing components as follows: 1. Any substitution allowed, as long as mechanically identical (non-electrical items only) (visually different ok) 2. Any susbstitution allowed, as long as mechanically similar (non-electrical items only) (visually different ok) 3. Any substitution, as long as mechanically and visually identical (non-electrical items only) 4. Any substitution allowed, as long as mechanically and visually similar (non-electrical items only) 5. Any substitution allowed, as long as mechanically and visually identical and electrically similar 6. Any substitution allowed, as long as mechanically, electrically and visually similar 7. Reserved for future usage. 8. Reserved for future usage 9. Substitution not recommended, but allowed if mechanically, electrically and visually similar. Only substitute if no alternative. 10. No substitution allowed. "Identical" is to be interpreted as "meeting the same specifications" with no deviation from the specifications. If no manufacturer is given, then do not deviate from stated specifications in the Description field. If a manufacturer is given, do not deviate from the specifications from the manufacturer--the Description field is for reference only then. "Similar" is to be interpreted as "meeting or exceeding the stated specifications, in regards to electrical and/or mechanical parameters (see Substitution code). ACS7xx Demo Board 85-0322-001-BOM Originator: Shawn Upton Bill of Materials Page 3 of 3 Rev 3 5/28/2008 If no manufacturer is given, then do not deviate from stated specifications in the Description field. If a manufacturer is given, do not deviate from the specifications from the manufacturer--the Description field is for reference only then. "Similar" as applied to visual means different colors may be used, unless otherwise noted. For example, an item with Substitution code 6 can typically be any color. However, if the description states "red" and the substitution code is 4, 6 or similar, then a red item must be used--but it may be any shade of red. For example, if a capacitor is to be "identical", it must have the same voltage and tempco etc ratings as stated in the description. If a capacitor is to be similar, the voltage rating may be higher, the tempco lower, etc. Unless if the Substitution code is 10, "identical" parts may be sourced from different manufacturers and may have slight differences in appearance. These subtle differences are ok. Substituting for "Similar" parts: Capacitors: -tempco must be same or go down. Alternately, go up in this order: Z5U, X5R, X7R, NP0, C0G -tolerance must be same or go down -voltage rating must be same or go up -unless otherwise stated, capacitance value must be identical -unless otherwise stated, lead spacing must be same; external dimensions must be the same or smaller Resistors: -tempco must same or go down -tolerance must be same or go down -unless otherwise stated, resistance value must be identical Note: when going from 5% to 1%, use nearest value size -power dissapation must be same or greater -unless otherwise stated, package size must be the same -unless otherwise stated, coloring and marking can vary Diodes and Transistors: -unless otherwise stated, package size must be the same IC's, Connectors, and all other parts:: -unless otherwise stated, package size must be the same (DIP16, SOIC-8, etc) Manufacturer Part Number Discrepencies Every attempt will be made to provide a workable part number. However, prefixes and suffixes can vary over time. If second sourcing from a different manufacturer, make sure that the requirements as noted under the Description column are met. In general, if temperature option(s) are not noted, parts specified to work from 0-85C will be sufficent. If package information is not given, please check the manufacturer datasheet for package type. Any and all descrepencies should be reported to Allegro MicroSystems for correction and updates. ACS7xx Demo Board 85-0322-010-BOM Originator: Shawn Upton ITEM QTY 1 2 1 1 S 10 10 Manufacturer Allegro Allegro Bill of Materials Page 1 of 1 P/N 85-0322-001 ACS712ELC-05B-T Rev 3 5/28/2008 DESCRIPTION board IC, SOIC8, current sensor All components and assembly practices must be RoHS Compliant Certificates of RoHS compliance must be sent to Allegro for record keeping REF U1 ACS7xx Demo Board 85-0322-011-BOM Originator: Shawn Upton ITEM QTY 1 2 1 1 S 10 10 Manufacturer Allegro Allegro Bill of Materials Page 1 of 1 P/N 85-0322-001 ACS712ELC-20A-T Rev 3 5/28/2008 DESCRIPTION board IC, SOIC8, current sensor All components and assembly practices must be RoHS Compliant Certificates of RoHS compliance must be sent to Allegro for record keeping REF U1 ACS7xx Demo Board 85-0322-012-BOM Originator: Shawn Upton ITEM QTY 1 2 1 1 S 10 10 Manufacturer Allegro Allegro Bill of Materials Page 1 of 1 P/N 85-0322-001 ACS712ELC-30A-T Rev 3 5/28/2008 DESCRIPTION board IC, SOIC8, current sensor All components and assembly practices must be RoHS Compliant Certificates of RoHS compliance must be sent to Allegro for record keeping REF U1 ACS7xx Demo Board 85-0322-013-BOM Originator: Shawn Upton ITEM QTY 1 2 1 1 S 10 10 Manufacturer Allegro Allegro Bill of Materials Page 1 of 1 P/N 85-0322-001 ACS713ELC-20A-T Rev 3 5/28/2008 DESCRIPTION board IC, SOIC8, current sensor All components and assembly practices must be RoHS Compliant Certificates of RoHS compliance must be sent to Allegro for record keeping REF U1 ACS7xx Demo Board 85-0322-014-BOM Originator: Shawn Upton ITEM QTY 1 2 1 1 S 10 10 Manufacturer Allegro Allegro Bill of Materials Page 1 of 1 P/N 85-0322-001 ACS713ELC-30A-T Rev 3 5/28/2008 DESCRIPTION board IC, SOIC8, current sensor All components and assembly practices must be RoHS Compliant Certificates of RoHS compliance must be sent to Allegro for record keeping REF U1
