All rights reserved. 22.May.2013.Rev.003 www.rohm.com TSZ22111 ・ 15 ・ 001 ● ● ● ● Circuit Applications 1) Examples of a common power supply detection reset circuit. Application examples of BD48Exxx-M series (Open Drain output type) and BD49Exxx-M series (CMOS output type) are shown on the left. CASE1: Power supply of the microcontroller (VDD2) differs from the power supply of the reset detection (VDD1). Use an open drain output type (BD48xxx-M) device with a load resistance RL attached as shown in figure 15. CASE2: Power supply of the microcontroller (VDD1) is same as the power supply of the reset detection (VDD1). Use a CMOS output type (BD49xxx-M) device or an open drain device with a pull up resistor between output and VDD1. 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). The Electrical characteristics were measured using RL= 470kΩ and CL = 100pF. 2) The following is an example of a circuit application in which an OR connection between two types of detection voltage resets the microcontroller. To reset the microcontroller when many independent power supplies are used in the system, OR connect an open drain output type (BD48Exxx-M series) to the microcontroller’s input with pull-up resistor to the supply voltage of the microcontroller (VDD3) as shown in Fig. 17. By pulling-up to VDD3, output “High” voltage of micro-controller power supply is possible.
