CMOS Voltage Detector (Reset) IC
BD52xx-2C Series and BD53xx-2C Series
General Description
Key Specifications
ROHM's BD52xx-2C and BD53xx-2C series are highly
accurate, low current consumption Voltage Detector
ICs with a capacitor controlled time delay. The lineup
includes N-channel open drain output (BD52xx-2C)
and CMOS output (BD53xx-2C) so that the users can
select depending on the application. The devices are
available for specific detection voltage ranging from
0.9V to 5.0V with 0.1V increment.
The time delay has ±50% accuracy in the overall
operating temperature range of -40°C to 125°C.
◼ Detection Voltage:

Caution: 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 and the internal circuitry. 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.

Application Information
1. Explanation of Operation
For both the open drain type (Figure 29) and the CMOS output type (Figure 30), the detection and release voltages
are used as threshold voltages. When the voltage applied to the VDD pin reaches the applicable threshold voltage,
the VOUT pin voltage switches from either “High” to “Low” or from “Low” to “High”. BD52xx-2C series and
BD53xx-2C series have delay time function which set tPLH (output “Low” to ”High”) using an external capacitor
connected in CT pin (CCT). Because the BD52xx-2C 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].

VOUT
Setting of Detector Delay Time
Delay time L to H (tPLH) is the time when VOUT rises to 1/2 of VDD after VDD rises up and beyond the release
voltage (VDET+∆VDET). The delay time (tPLH) at the rise of VDD is determined by delay coefficient, CT capacitor and
delay time when CT pin is open (tCTO) and calculated from the following formula. When CT capacitor ≥ 1nF, tCTO has
less effect and tPLH computation is shown on Example No.2. The result has ±50% tolerance within the operating
temperature range of -40°C to +125°C
Formula: (Ta=25°C)
𝑡𝑃𝐿𝐻 = 𝐶𝐶𝑇 × 𝐷𝑒𝑙𝑎𝑦 𝐶𝑜𝑒𝑓𝑓𝑖𝑐𝑖𝑒𝑛𝑡 + 𝑡𝐶𝑇𝑂
[s]
where:
CCT is the CT pin external capacitor
Delay Coefficient is equal to 5.55 x 106
tCTO is the delay time when CT=open Note1

Example No.1:
CT capacitor = 100pF
𝑡𝑃𝐿𝐻_𝑚𝑖𝑛 = (100 × 10−12 × 5.55 × 106 ) × 0.5 + 15 × 10−6 = 292µ𝑠
𝑡𝑃𝐿𝐻_𝑡𝑦𝑝 = (100 × 10−12 × 5.55 × 106 ) × 1.0 + 50 × 10−6 = 605µ𝑠
𝑡𝑃𝐿𝐻_𝑚𝑎𝑥 = (100 × 10−12 × 5.55 × 106 ) × 1.5 + 150 × 10−6 = 983µ𝑠
Example No.2:
CT capacitor = 1nF
𝑡𝑃𝐿𝐻_𝑡𝑦𝑝 = 1 × 10−9 × 5.55 × 106 = 5.55𝑚𝑠
