Features, Applications

Rohm's BD48XXG/FVE and BD49XXG/FVE are series of high-accuracy, low-power VOLTAGE DETECTOR ICs with a CMOS process. For flexible choice according to the application, BD48XXG/FVE series with N channel open drain output and BD49XXG/FVE series with CMOS output are available in 38 voltage types from V in steps V in different packages, totaling 152 models.

Applications Every kind of appliances with microcontroller and logic circuit

Features 1) Detection voltage: 0.1V step line-up 2.3~6.0V (Typ.) 2) High-accuracy detection voltage: 1.5% guaranteed (Ability 1%) 3) Ultra low current consumption: 0.8A typ. (Output is High.) 4) Nch open drain output (BD48XXG/FVE series), CMOS output (BD49XXG/FVE series) 5) Small package : BD48XXG/BD49XXG Selection guide For BD4XXXX series, detection voltage, output circuit types (Refer to the block diagram at P3), and package (Refer to the dimension at P14) can be selected for your own application. Part number of devices for each specification is shown below.

1 Part No. 2 3 Specification Output circuit types Detection voltage Package 2 3 Contents 8 : Open drain output 9 : CMOS output Ex. VS : described in each 0.1V step for 2.3V~6.0V range (29 means SSOP5 (SMP5C2) FVE VSOF5 (EMP5)

Pin layout Pin layout of VSOF5(EMP5) and SSOP5(SMP5C2) is different as shown below. (Fig.1, Fig.2) When used as replacement, please consider the difference. (The detail of packages is shown at P14.)

Block diagram Two output types can be used. One (Fig.3) of open drain output type, and the other (Fig.4) of CMOS output type.

Absolute maximum rating (Ta=25C) To prevent the functional deterioration or thermal damage of semiconductor devices and ensure their service life and reliability, they must be designed and reviewed in such a way that the absolute maximum rating can not be exceeded in any cases or even at any moment.

Parameter Power supply voltage Output Nch Open drain output voltage CMOS output 1 Power dissipation *3 2 Power dissipation * *3 Operating temperature Storage temperature

*1 Derating : 1.5mW/C for operation above Ta=25C *2 Derating : 1.0mW/C for operation above Ta=25C *3 When only IC is used.

Power supply voltage This voltage is the applied voltage between VDD and GND. The applied voltage should not exceed the indicated value. Output voltage VOUT pin voltage should not exceed the indicated value. For Nch open drain output type, VDD applied voltage and VOUT pin H output voltage can be used independently. Both of them should not exceed the each indicated value. Operating temperature range The circuit function is guaranteed within the temperature range. However, the operating characteristics are different from that Ta=25C. If they are any questions about the extent of guarantee of circuit functions in this operating temperature range, please ask for more technical information. Storage temperature range This IC can be stored up to this temperature range without deterioration of characteristics. However, an abrupt thermal shock of extreme temperature fluctuations may cause the deterioration of characteristics.
