DS40235B-page 1 PS4160 The PS4160 module is a complete smart battery controller subsystem with safety based on the Microchip PS401 battery manager with patented Accuron technology. The module is designed to operate in a battery pack consisting of three 3 or four 4 series connected Lithium cells. The module consists of three circuit sections the Microchip PS401 battery manager IC, Mitsumi MM1414 based primary safety circuit and a secondary safety circuit controlled by the PS401 to provide backup to the MM1414. Quick Start Pack Assembly Follow these directions to assemble a pack with the PS4160 module. • Use standard precautions when handling static sensitive devices. • Modules should be connected to battery cells in the order indicated below to insure proper start-up and operation. Wires should be attached to the modules first and then connected to the battery cells as instructed. • The connection sequence is critical to successful use of the PS401 family of CMOS ASICs. Pack positive should always be connected first, followed by the intermediate cell voltages from highest to lowest, and finishing with the negative end of the pack. Step 1 Configure the module for the number of series cells according to the following chart: Li Ion 3-cell Removed Installed Installed Li Ion 4-cell Installed Removed Step 2 Configure the module for the following options. Use Optional External Thermistor The PS401 IC has an integrated temperature sensor. If you would like to add an optional external thermistor, remove R16. Charge FET Control The PS4160 is shipped with the Mitsumi 1414 IC controlling both the charge and discharge FETs. If you would like to enable PS401 control of the charge FET, remove R25 and change the value of bit 2 of the FLAGS1 parameter to Setting bit 2 of FLAGS1 disables the GPIOs. GPIO<3:0> Operation: The PS4160 is shipped with four LEDs for a SOC display. These LEDs are connected to GPIO<3:0> pins on the PS401 IC. The GPIO<3:0> pins can be used for operation other than the LED SOC display by removing the LED and monitoring the adjacent test point. Step 3 Connect wires to module. Use large diameter wire 18AWG-20 AWG for current carrying lines from VR and V1. All others are signal only lines 24 to 22 AWG . Step 4 Connect V1 to the most positive point on the battery cell stack. Step 5 Connect cell voltage pickups 4 series cells negative end of topmost cell in stack to V2, negative end of next cell to V3, and negative end of third cell to V4. 3 series cells negative end of topmost cell in stack to V2, negative end of next cell to V3, no connection at V4. Step 6 Connect VR to the most negative point on the battery cell stack. Step 7 Connect external connector to B-Neg, T, C, D and B+. Step 8 The PS4160 is shipped with the secondary safety circuit disabled to avoid damage to the fuse during assembly. To enable the secondary safety circuit, remove R23 and change the value of bit 2 of the FLAGS1 parameter to Setting bit 2 of FLAGS1 disables the GPIOs configured for safety. Step 9 Program the assembled pack using Microchip's PowerTool software and PowerCal board or PowerInfo board hardware. The EEPROM parameters can be changed at will using the utilities on the P4 EE page in the PowerTool software. The OTP EPROM parameters can be changed a limited number of times using utilities on the P4 OTP page. To write to the OTP EPROM, an additional voltage VPP must be applied to the PS401. This programming voltage can be obtained from the PowerInfo board and applied to the PS4160 at connection VP small thru-hole located on the small edge of the board opposite the connector edge. Step 10 Calibrate the pack using the PowerTool software and PowerCal board hardware. The pack is now ready for use. DS40235B-page 2 2003 Microchip Technology Inc.
