FunctionDescription TheDIO1412is temperaturesensorchipcompatiblewith SMBus (orI2C)communicationprotocol.Thechipcan monitor one internal temperature and can also monitor one external channel. The external channel can support both PNP and diode-connected NPN temperature monitoring. The ALERT or THERM/ADDR pin can be assertedtoachievetwolevels ofovertemperaturealarm. 9.1. Operatingmodes TheDIO1412havetwooperatingmodes,standbyandactive. Inthestandbymode,thechipsupportsSMBusandI2Cbutdoesnotconductconsecutivetemperaturedetection. Every time the one shot register is written (see section 12.7), the device detects all temperature channels for once.Afterthetemperaturedetectioniscompleted,thedeviceentersthestandbymodeagain. In the active mode, the chip performs consecutive temperature detection and updates the temperature data in theregisters andthevalueofthestatus registers(seesection 12.2) inreal-time.Thisis thedefaultstate. 9.2. Externaltemperaturedetection The DIO1412 can automatically detect whether the externally connected BJTis NPN or PNP.If the BJTis PNP, the chip will automatically detect the beta value of PNP to configure the appropriate working state, so as to achievethehighaccuracyoftemperaturemeasurement(seesection12.1). When the external PNP for temperature monitoring is a parasitic PNP with a low beta value, which will greatly affect the accuracy of temperature measurement, the Beta Compensation will be enabled to reduce the temperatureerrors. Inapplications,thetemperaturemeasurementaccuracymaybeaffectedbytheseriesresistancesintroducedby the long trace on the PCB and the welding resistances at the ports. The Resistance Error Correction integrated intotheDIO1412canminimizethetemperatureerrorscausedbythese seriesresistances. The non-ideal factor, η, varies with different types of BJTs will also affect the accuracy of external temperature measurement.The DIO1412 has individual non-ideal factor configuration register for each channel (see section 12.3),thevalueofwhichcanbeprogrammedbytheusertoobtainaccuracytemperaturemonitoring. 9.3. Overtemperaturealarm The DIO1412 has THERM/ADDR output pin and ALERT output pin for overtemperature alarm or fault event. Both THERM/ADDRand ALERT pinsareopen-drainoutputs andrequirepull-upresistors. 9.3.1. ALERT pin The ALERT pin is an open-drain output, so that a pull-up resistor is needed. It has two modes of operation, named “Interrupt mode” and “Comparator mode”, which can be selected via the ALERT/COMP bit in the ConfigurationRegister(seesection 12.3). 9.3.2. Interruptmode In the interrupt mode, the ALERT pin is asserted when any channel’s temperature measuring consecutively out-of-limit(≥HighLimitor <Low Limit) conditionsor faultconditionsis detectedfortheprogrammednumberof
Version1.0,Jul2024 www.dioo.com ©2024DIOOMICROCIRCUITSCO.,LTD. times. The ALERT pin will remain asserted as long as an out-of-limit condition remains. Once the out-of-limit condition has been removed, the ALERT pin will remain asserted until the appropriate status bits are cleared. TheappropriatestatusbitsincludeExternalfaultsstatus,HighLimitstatusandLowLimitstatusbits,allofwhich arereadclear (seesection 12.10). The ALERT pin can be masked by setting the MASK_ALLbit or channel mask register. Once the ALERT pin hasbeenmasked,itwillbedeassertedandremaindeasserteduntiltheMASK_ALLbitorchannelmaskregister is cleared by the user.Nomatter MASK_ALLbit or channel mask register is set or not, the status registers (see secton11.2)willbeupdated normally. The ALERT pin can be used as an interrupt signal or as an SMBusAlert signal, which allows an SMBus client toreportanerrorconditiontothe host.Oneormore ALERT outputscanbehard-wiredtogether. 9.3.3. Comparatormode In the comparator mode, the ALERT pin will be asserted if any of the measured temperature exceeds the programmedHigh Limitfor the programmed number of times in a consecutive measurements.The ALERT pin willremainasserteduntilall themeasuredtemperaturesdropbelowtheHighLimitminustheThermHysteresis. In the comparator mode, the ALERT pin cannot be masked by MASK_ALL bit or channel mask register. The corresponding High Limit status bits will not be cleared until the ALERT pin is deasserted. Once the ALERT pinisdeasserted,theHighLimitstatusbitswillbeautomaticallycleared. 9.3.4. THERM pin Theoutputofthe THERM/ADDR pincannotbemasked.Whenthetemperatureofany channel isconsecutively detected exceeding the programmed Therm Limit for the programmed number of consecutive measurements, the THERM/ADDR pin will be asserted. And the THERM/ADDR pin will remain asserted until the measured temperatures that cause a thermal overtemperature event drop below the programmed Therm Limit minus the Therm Hysteresis, and no other channel’s measured temperature consecutively detected exceeding the programmedThermLimitfortheprogrammednumberofconsecutivemeasurements. Whenthe THERM/ADDRpinisasserted,boththeregisterThermLimitStatusbits(seesection12.8)andStatus bits (see section 12.2) will be set. These bits are not read clear and will only be clear when the THERM/ADDR pinisdeasserted. 9.4. Openandshortfaults Before monitoring the temperature on each external channel, the DIO1412 checks whether the BJT on the externalchannelisproperlyconnectedtotheDPandDNports.Thefollowingtwoconnectionsareconsideredto befaults: DPtoDNis open; DPor DNisshorttoVDD. Whenafaultistriggered,thecorrespondingfaultstatusregisterisset,andthe ALERT pinwillbeasserted.The 12-bittemperaturereadingforthecorrespondingchannelis000000000000.Whenthechannelfaultisdetected, thecorrespondingchannel’sLowLimitwill notbechecked.

Version1.0,Jul2024 www.dioo.com ©2024DIOOMICROCIRCUITSCO.,LTD. 11. CommunicationProtocolandSMBusProtocol 11.1. Communicationprotocol Through the SMBus (or I2C), the DIO1412 can communicate with the host controller.The SMBus is a two-wire serial communication protocol between a computer host and its peripheral devices. The details can be found in theFigure1. 11.1.1. SMBus address and RD/ WRbit The SMBus address byte consists of the 7-bit client address followed by the RD/ WR indicator bit. To the client device,theRD/ WRbitcanbeeitherwriting orreadingdate. WhentheRD/ WRbitisalogic‘0’,theSMBushostiswritingdata.WhentheRD/ WRbitisalogic‘1’,theSMBus hostis readingdata. The DIO1412CSMBus slave address is determined by the pull-up resistor on the THERM/ADDR pin as shown intable5insection9.8"ProgrammingSMBus (orI2C)Address". 11.1.2. SMBus databytes All SMBus data bytes are composed of 8-bits of information and sent in order of priority, which means they are sentmostsignificantbitatfirst. 11.1.3. SMBusACKandNACK bits Allreceived databytesareacknowledgedby theSMBusclient.Thisisaccomplishedbytheclientdevicepulling theSMBusdata linelowaftereachsentbyte's eighthbit.This is trueoftheWriteByteprotocol. BykeepingtheSMBusdata linehighafterthe8thdata bithas beensent,thehostwillNACK (notacknowledge) thefinaldatabytethathasbeenreceivedfromtheclient. 11.1.4. SMBus timeout SMBus timeout function is supported by the DIO1412. The device resets its SMBus protocol if the clock line is maintained low for more than 30 ms. Setting the TIMEOUT bit in the consecutive ALERT register (see section 12.11)willenablethisfunction. 11.1.5. SMBus andI2Ccompatibility SMBus and I2C are both supported by the DIO1412. Here shows the key differences between SMBus and I2C devices. TheDIO1412supportsI2Cfastmodeat400kHz,covering100kHz(maximumSMBus time). (1) 10kHzistheminimumfrequencyforSMBuscommunications. (2) The condition of resetting the SMBus client protocol is that the clock is kept at a logic “0” for longer than 30 ms. The timeout functionality is disabled by default while it is enabled by writing to the bit 7 in the consecutive ALERTregister (TIMEOUTbit).I2Cdoesn’thaveatimeout. (3) I2Cdevicescan’tsupporttheALERTresponseaddressfunctionalityand it’soptionalforSMBus. The DIO1412 SMBus interface will not respond to signals sent with an invalid slave address or an invalid protocol, and the register contents will remain unaffected. Stretching of the SMCLK signal is supported if the timingis managedbyotherSMBus components.
Version1.0,Jul2024 www.dioo.com ©2024DIOOMICROCIRCUITSCO.,LTD. 11.2. SMBusprotocol The DIO1412 supports various kind of byte protocols: Send bite, Read byte, Write byte, Receive byte andAlert responseaddressas validprotocols. (1) Writebyte:Writingonebyteofdatatotheregisters. (2) Readbyte:Readingonebyteofdata fromtheregisters. (3) Sendbyte:Settingtheinternaladdressregisterpointertothecorrectaddresslocation.Notedthat nodatais transferredduringtheSendbyteprotocol. (4) Receive byte: Reading data from a register when the internal register address pointer is at the correct locationviaSendbyte.Thisis usedforconsecutivereads ofthe sameregister. (5) Alert response address: the ALERT pin output can be interpreted as interrupt or as an SMBusAlert by the host. When the ALERT pin is asserted, the host will send the Alert Response Address (ARA) to the general addressof0001_100xb.TheDIO1412willrespondtotheARAintwosteps:sendtheslaveaddressofDIO1412.

ConsecutiveALERTregister The consecutiveALERTregister is used to choose how many times an out-of-limit (≥ High Limit or < Low Limit) condition or fault condition have been detected in consecutive measurements before the THERM/ADDR pin is asserted. Additionally, the TIMEOUT bit (B7) is used to enable or disable the SMBus timeout.

When the ALERT pin is configured in the interrupt mode, if any consecutive alert counter reaches its programmed value, the STATUS bit for the corresponding channel and the last out-of-limit condition or fault condition will be set to ‘1’. And the ALERT pin will be asserted. Then the consecutive alert counter will be cleared. When the ALERT pin is configured in comparator mode, the consecutive alert counter will be increased by 1 only when the measured temperature exceeds the High Limit. Once the consecutive alert counter reaches the programmedlimit,the ALERT pinwillbeasserted.However,theconsecutivealertcounterwillnotbereset.And itwillremainsetuntilthetemperaturedrops belowtheHighLimitminus theThermHysteresis.
