Also, discussed are the protection circuits that can shut down each block to prevent IC destruction. All output voltages generated by each block, startup order, and delay time (DELAY1 and DELAY2) can be set through the EEPROM. Upon start-up, these settings are read from the EEPROM and copied to the registers. ① Buck Converter Block (VDD1, VDD2) Generates the VDD1 and VDD2 voltages after VCC UVLO release at EN=High. This block shuts down when SCP or OCP is detected. ② Boost Converter Block (AVDD) Generates the AVDD voltage after the configured DELAY2 time. This block shuts down when OVP, SCP, or OCP is detected. ③ HAVDD Amp Block (HAVDD) Generates the HAVDD voltage based on the AVDD voltage. Thus, the HAVDD voltage is produced after the AVDD voltage. ④ VCOM Amp Block (VCOM) Generates the VCOM voltage based on the AVDD voltage. Thus, the VCOM voltage is produced after the AVDD voltage. ⑤ Positive Charge Pump Block (VGH) Generates the VGH voltage based on the AVDD voltage. Thus, the VGH voltage is produced after the AVDD voltage. This block shuts down when SCP is detected. ⑥ Negative Charge Pump Block (VGL) Generates the VGL voltage based on the AVDD voltage. It starts up after the configured DELAY2 time. This block shuts down when SCP is detected. www.rohm.com © 2013 ROHM Co., Ltd. All rights reserved.

ILR IOMAXMean current t Fig.52 Inductor Current Waveform (Buck Converter : VDD) The output inductance (L) is decided by the rated current (ILR) and maximum input current (IOMAX) of the inductance. Adjust so that IOMAX + ∆IL / 2 does not reach the rated current value. ∆IL can be obtained by the following equation. 1 VO 1 ∆IL = × (VIN - VO) × × [A] L VIN f where f is the switching frequency Set with sufficient margin because the inductance value may have a dispersion of ±30%. If the coil current exceeds the rated current (ILR), the IC may be damaged. The output capacitor (CO) smoothens the ripple voltage at the output. Select a capacitor that will regulate the output ripple voltage within the specifications. Output ripple voltage can be obtained by the following equation. ∆IL VO 1 ∆VPP = ∆IL × RESR ＋ 2 Co × VIN × f However, since the aforementioned conditions are based on a lot of factors, verify the results using the actual product. www.rohm.com © 2013 ROHM Co., Ltd.

The device/slave address is always followed by the 1 byte register/select address as shown in the I2C bus format below. MSB LSB Device address Start A6 A5 A4 A3 A2 A1 A0 Start Device Address : : ACK : Register Address Data STOP : : : MSB R/W ACK LSB MSB Register address R7 R6 R5 R4 R3 R2 R1 ACK R0 LSB Data D7 D6 D5 D4 D3 D2 D1 D0 ACK STOP Start bit Consists of 8 bits in total (A6 to A0 and the R/W bit) (MSB fast). If the R/W bit is H, this means read mode. If the R/W bit is L, this means write mode. Acknowledge bit. When sending and receiving data, there should be an acknowledge bit after each byte. If data is sent and received properly, ‘L’ is replied to the sender. If data is not received properly, ‘H’ is replied to the sender. 1 byte select address. Data byte. Sending and Receiving data (MSB Fast) Stop bit There are two writing modes from I2C bus to the registers, single mode and multi mode. In single mode, communication is sent to a single register. In multi mode, communication is sent to multiple registers by entering multiple data before the stop bit. ●Device address Slave address specific to the IC is 1000000 (A6 to A0). ●Register address R7 is for TEST MODE. Normally, this should be set to 0. R6 and R5 are don’t care bits. R4 to R0 are the register address bits. ●Command interface Transmission format for data sent and received to the EEPROM is shown below.

The logic of the register address R4 will determine where the data will be written. Check-sum is installed before writing data to prevent malfunctions caused by data error. The flowchart of the writing process to the register and EEPROM is shown below. Device Address 1000 000x Read/ Write? Write Read Register DATA OUTPUT 01h～09h 0000 xxxx 01h～08h CHK_SUM REG ADDRESS 01h～08h/09h? NG 09h REG ADDRESS R4 is ? 0001 xxxx 11h～18h REG ADDRESS 11h～18h/19h? CHK_SUM SHUTDOWN NG 19h SHUTDOWN OK Write Register (01h～08h) Write Register (09h) Write EEPROM (01h～08h) Write EEPROM (09h) ・Writing Data to the Register Data is written to the registers when register address R4 is “0”. AVDD, VGH, VGL, HAVDD, and VCOM (register address: 01h to 04h) output voltage can be changed by writing data to the registers. ・Writing Data to the EEPROM Data is written to the EEPROM when register address R4 is “1”. Upon start-up and EN is high, data which is stored in the EEPROM is copied to the registers. Therefore, by writing to the EEPROM, the start-up settings will be changed. www.rohm.com © 2013 ROHM Co., Ltd. All rights reserved. TSZ22111・15・001 31/44 TSZ02201-0313AAF00430-1-2 12.May.2015 Rev.003 Datasheet BM81028AMWV ●Automatic EEPROM Read Function at Start-up Upon BD81028AMWV start-up, a reset signal is generated and each register is initialized. After that, when EN is changed from low to high, data which is stored in the EEPROM is copied to the registers. Furthermore, the check-sum function is installed to prevent malfunctions caused by data error. The automatic EEPROM read function at start-up is further explained by the flow chart below. ●Check-Sum Data If data is written to the Register and EEPROM, it is necessary to set check-sum data to prevent malfunctions caused by data error. Check-sum data is the complement of the sum of all data. When check-sum data is added to the sum of all data, the result should be zero.

There are two ways to reactivate the PMIC. First, write to the EEPROM the correct data while the power supply is turned on and EN=L; then toggle EN to H. Lastly, reset the power supply and enter the correct data while EN=H. www.rohm.com © 2013 ROHM Co., Ltd. All rights reserved.

Because FAULT is an open-drain output, place a pull-up resistor externally. When the FAULT output will not be used, connect to GND. 10kΩ to 220kΩ FAULT Fig. 55 FAULT Output FAULT=H During stable operation when none of the protection circuits are in effect. This is due to the external pull-up resistance. FAULT=L When any of the protection circuits (UVLO, OCP, OVP, TSD, and SCP) are triggered. This indicates a circuit error. The recommended external pull-up resistance for the FAULT output is 10kΩ to 220kΩ. An external resistance of under 10kΩ can generate an offset voltage during FAULT=L caused by the voltage drop across the internal on resistance. On the other hand, an external resistance of more than 220kΩ can interfere with the output during FAULT=H because of leak current. www.rohm.com © 2013 ROHM Co., Ltd. All rights reserved.

In addition, it is impossible to predict all destructive situations such as short-circuit modes, open circuit modes, etc. Therefore, it is important to consider circuit protection measures, like adding a fuse, in case the IC is operated in a special mode exceeding the absolute maximum ratings. 2) Ground potential The voltage of the ground pin must be the lowest voltage of all pins of the IC at all operating conditions. Ensure that no pins are at a voltage below the ground pin at any time, even during transient condition. 3) Thermal consideration Use a thermal design that allows for a sufficient margin by taking into account the permissible power dissipation (Pd) in actual operating conditions. 4) Short between pins and mounting errors Be careful when mounting the IC on printed circuit boards. The IC may be damaged if it is mounted in a wrong orientation or if pins are shorted together. Short circuit may be caused by conductive particles caught between the pins. 5) Operation under strong electromagnetic field Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction. 6) Testing on application boards When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply should always be turned off completely before connecting or removing it from the test setup during the inspection process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and storage. 7) Regarding input pins of the IC This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a parasitic diode or transistor. For example (refer to figure below): When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode. When GND > Pin B, the P-N junction operates as a parasitic transistor. Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be avoided. Resistor Transistor (NPN) Pin A Pin B C Pin B B Pin A N P+ N P+ P N E Parasitic element N P+ N P P substrate Parasitic element GND P B + N E P substrate Parasitic element GND C GND Parasitic GND element Other adjacent elements Example of a Simple Monolithic IC Structure 8) Over-current protection circuit (OCP) The IC incorporates an over-current protection circuit that operates in accordance with the rated output capacity. This circuit protects the IC from damage when the load becomes shorted. It is also designed to limit the output current (without latching) in the event of a large transient current flow, such as from a large capacitor or other component connected to the output pin. This protection circuit is effective in preventing damage to the IC in cases of sudden and unexpected current surges. The IC should not be used in applications where the over current protection circuit will be activated continuously. 9) Thermal shutdown circuit (TSD) The IC incorporates a built-in thermal shutdown circuit, which is designed to turn off the IC when the internal temperature of the IC reaches a specified value. It is not designed to protect the IC from damage or guarantee its operation. Do not continue to operate the IC after this function is activated. Do not use the IC in conditions where this function will always be activated. 10) DC/DC switching line wiring pattern DC/DC converter switching line (wiring from the switching pin to inductor, Nch MOS) must be as short and thick as possible to reduce line impedance. If the wiring is long, ringing caused by switching would increase and this may exceed the absolute maximum voltage ratings. If the parts are located far apart, consider inserting a snubber circuit. www.rohm.com © 2013 ROHM Co., Ltd. All rights reserved.
