●Application Information
Explanation of Operation
For both the open drain type (Fig.12) and the CMOS output type (Fig.13), the detection and release voltages are used as
threshold voltages. When the voltage applied to the VDD pins reaches the applicable threshold voltage, the VOUT terminal
voltage switches from either “High” to “Low” or from “Low” to “High”. Please refer to the Timing Waveform and Electrical
Characteristics for information on hysteresis. Because the BD48Exxx-M series uses an open drain output type, it is
necessary to connect a pull-up resistor to VDD or another power supply if needed [The output “High” voltage (VOUT) in this
case becomes VDD or the voltage of the other power supply].

When the power supply is turned on, the output is unstable
from after over the operating limit voltage (VOPL) until tPHL.
Therefore it is possible that the reset signal is not valid when the
rise time of VDD is faster than tPHL.
2 When V
DD is greater than VOPL, but less than the reset release
voltage (VDET + ∆VDET), the output voltages will switch to Low.
3 If V
DD exceeds the reset release voltage (VDET + ∆VDET), then,
VOUT switches from L to H.
4 If V
DD drops below the detection voltage (VDET) when the power
supply is powered down or when there is a power supply
fluctuation, VOUT switches to L (with a delay of tPHL).
5 The potential difference between the detection voltage and the
release voltage is known as the hysteresis width (∆VDET).
The system is designed such that the output does not toggle with
power supply fluctuations within this hysteresis width, preventing
the
malfunctions due to noise.

3) Examples of the power supply with resistor dividers
In applications wherein the power supply voltage of an IC comes from a resistor divider circuit, an in-rush current will flow into
the circuit when the output level switches from “High” to “Low” or vice versa. In-rush current is a sudden surge of current that
flows from the power supply (VDD) to ground (GND) as the output logic changes its state. This current flow may cause
malfunction in the systems operation such as output oscillations, etc.

Fig.18
When an in-rush current (I1) flows into the circuit (Refer to Fig. 18) at the time when output switches from “Low” to “High”,
a voltage drop of I1×R2 (input resistor) will occur in the circuit causing the VDD supply voltage to decrease. When the VDD
voltage drops below the detection voltage, the output will switch from “High” to “Low”. While the output voltage is at “Low”
condition, in-rush current will stop flowing and the voltage drop will be reduced. As a result, the output voltage will switches
again from “Low” to “High” which causes an in-rush current and a voltage drop. This operation repeats and will result to
oscillation.

●Operational Notes
1) Absolute maximum ratings
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit
between pins or an open circuit between pins. Therefore, it is important to consider circuit protection measures, such
as adding a fuse, in case the IC is operated over the absolute maximum ratings.
2)
Ground Voltage
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)
Recommended operating conditions
These conditions represent a range within which the expected characteristics of the IC can be approximately obtained.
The electrical characteristics are guaranteed under the conditions of each parameter.
4)
Bypass Capacitor for Noise Rejection
To help reject noise, put a 1µF capacitor between VDD pin and GND and 1000pF capacitor between VOUT pin and GND.
Be careful when using extremely big capacitor as transient response will be affected.
5)
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.
6)
Operation under strong electromagnetic field
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.
7)
The VDD line impedance might cause oscillation because of the detection current.
8)
A VDD to GND capacitor (as close connection as possible) should be used in high VDD line impedance condition.
9)
Lower than the mininum input voltage puts the VOUT in high impedance state, and it must be VDD in pull up (VDD)
condition.
10) External parameters
The recommended parameter range for RL is 10kΩ to 1MΩ. There are many factors (board layout, etc) that can affect
characteristics. Please verify and confirm using practical applications.
11) Power on reset operation
Please note that the power on reset output varies with the VDD rise time. Please verify the behavior in the actual
operation.
12) 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.
13) Rush current
When power is first supplied to the IC, rush current may flow instantaneously. It is possible that the charge current to
the parasitic capacitance of internal photo diode or the internal logic may be unstable. Therefore, give special
consideration to power coupling capacitance, power wiring, width of GND wiring, and routing of connections.
14) This IC has extremely high impedance terminals. Small leak current due to the uncleanness of PCB surface might
cause unexpected operations. Application values in these conditions should be selected carefully. If 10MΩ leakage is
assumed between the CT terminal and the GND terminal, 1MΩ connection between the CT terminal and the VDD
terminal would be recommended. Also, if the leakage is assumed between the Vout terminal and the GND terminal, the
pull up resistor should be less than 1/10 of the assumed leak resistance.
