BD5353G-TR

BD5353G-TR is part of the ROHM\'s series of low voltage supervisors for microcomputer reset, utilizing a highly reliable CMOS process. This device has an operating voltage range of 1.1V to 5.5V, making it suitable for a variety of applications from automotive to consumer electronics. Furthermore, it offers a great power-saving performance while resetting the input signal.

The BD5353G-TR is a single-input supervisory circuit that monitors power supply voltages, preventing system failure due to low battery voltage. It starts up quickly, increasing system reliability and providing a reset signal when the voltage falls below the preset level. The reset signal is output by two devices, the RST output pin and the interrupt output pin. The reset output pin is used when the power supply voltage drops within the specified range. The interrupt output pin is used when the voltage has dropped below a prescribed limit.

The main features of BD5353G-TR include a low power shutdown feature that shuts down the reset output pin when the power supply voltage drops below the specified level, an interrupt output pin that starts up quickly and prevents system failure due to low battery voltage, an adjustable upper and lower operating voltage of 1.1V to 5.5V, an active-low reset output that triggers a reset when the voltage drops below a user-defined level, and an integrated power-on reset circuit that can be used to detect when power is applied. It also features a watchdog timer for resetting a target system if it fails to respond to a request signal within a set amount of time.

The working principle of BD5353G-TR is simple. When the power supply voltage drops below the set level, the device will output a reset signal which then triggers an interrupt. After the reset signal is generated, the device then begins to monitor the power supply voltage again to ensure that it remains within the specified range. If the voltage falls below the set level again, the reset signal will be generated. The device will continue to monitor the power supply voltage until it reaches the normal operating level. Once it has reached the normal operating voltage level, the reset signal will be cleared, allowing the system to continue functioning properly.

BD5353G-TR is suitable for applications such as automotive, consumer electronics, and other industrial applications where voltage and current monitoring is required. The device is available in both SOT-23-5 and SOP-16 packages, making it compatible with a range of systems and applications. Its robust features, such as low power consumption, an adjustable upper and lower operating voltage range, and an integrated power-on reset circuit, make it an ideal choice for applications that require reliable voltage monitoring.

In conclusion, BD5353G-TR is a reliable single-input supervisory circuit specifically designed to monitor power supply voltages, preventing system failure due to low battery voltage. Its low power consumption, adjustable upper and lower operating voltage range, and integrated power-on reset circuit make this device ideal for applications such as automotive, consumer electronics, and other industrial applications where voltage and current monitoring is required.
