Circuit Applications
1) Examples of a common power supply detection reset circuit.
Application examples of BD48
□□G/FVE series (Open
Drain output type) and BD49
□□G/FVE series (CMOS
output type) are shown below.
CASE1: the power supply of the microcontroller (VDD2)
differs from the power supply of the reset detection
(VDD1).
Use the open drain output type (BD48
□□G/FVE) attached
a load resistance (RL) between the output and VDD2. (As
shown Fig.15)
CASE2: the power supply of the microcontroller (VDD1) is
same as the power supply of the reset detection (VDD1).
Use CMOS output type (BD49
□□G/FVE) or open drain
output type (BD48
□□G/FVE) attached a load resistance
(RL) between the output and Vdd1. (As shown Fig.16)
When a capacitance CL for noise filtering is connected to
the VOUT pin (the reset signal input terminal of the
microcontroller), please take into account the waveform of
the rise and fall of the output voltage (VOUT).
2) The following is an example of a circuit application in which an OR connection between two types of detection voltages
resets the microcontroller.
When there are many power supplies of the system, power supplies VDD1 and VDD2 are being monitored separately, and
it is necessary to reset the microcomputer, it is possible to use an OR connection on the open drain output type
BD48
□□G/FVE series to pull-up to the desired voltage (VDD3) as shown in Fig.17 and make the output “High” voltage
matches the power supply voltage VDD3 of the microcontroller.
