The ROHM Semiconductor BD87A41FVM-TR is a silicon monolithic integrated circuit belonging to the BD87Axx series of watchdog timer reset ICs. It provides a high precision detection voltage with a typical accuracy of ±1.5% at 25°C, and ±2.5% across the operating temperature range of -40°C to 105°C. This device features super-low current consumption of 5µA (Typ).
Key features include a built-in watchdog timer and an open-drain output circuit. The reset delay time and watchdog timer monitor time can be set using external capacitors connected to the CT and CTW pins, respectively. The device operates with a power supply voltage range of 1.0V to 10V for reset functions and 2.5V to 10V for the watchdog timer.
Applications for this IC include all devices using microcontrollers or DSPs, such as vehicle equipment, displays, servers, DVD players, and telephone systems. It is supplied in an 8-MSOP package suitable for surface mounting.
The BD87A41FVM-TR is designed to monitor power supply voltages and ensure system stability, making it a crucial component in embedded systems requiring reliable operation.
