The XC6126 series is an ultra-small, high-precision CMOS single-voltage detector with extremely low power consumption. The unit includes a high-precision voltage reference source that uses laser trimming technology to maintain high accuracy over the entire operating temperature range. The device is available in CMOS and n-channel open-drain output configurations. The ultra-small package USPN-4B02 is ideal for small portable equipment designs and high-density mounting applications. The legacy software package SSOT-24 is also available for upper-layer compatible replacement.

When using an N-ch open-drain output, the VOUT voltage at detection is determined by a pull-up resistor connected to the output pin. Resistors are selected based on the following considerations:

On Detection: Output Voltage = (Vpull-Up) / (1 + Rpull / Ron) Vpull-Up: Voltage After Pulling Ron (*_1): Resistor N-ch Driver (Calculate Output Voltage/IOUT1 Based on Electrical Characteristics) (*_3) Example: When VIN = 2.0 v(*_2), Ron = 0.5/4.5×three points≒111Ω(MAX). If you want to output voltage at detection voltage of 0.1 V or less Vpull-Up 3.0 V, Rpull = (Vpull-Up / VOUT-1) × Ron = (3/0.1-1) × 111≒ 3.2 kΩ Therefore, make the detection For an output voltage of 0.1 V or less under the above conditions, the pull-up resistor must be k~3.2 or higher. (*1) Note that as VIN becomes smaller, RON also becomes larger. (*2) When calculating VIN, use the minimum value of the input voltage range you will use. (*3) The electrical characteristics of IOUT1 are Ta = 25°C. IOUT1 varies with ambient temperature. To choose a pull-up resistor considering the ambient temperature, please consult us
