The BD87A29FVM-TR from ROHM Semiconductor is a silicon monolithic integrated circuit functioning as a watchdog timer reset IC. It is designed to monitor power supply voltages and ensure system stability, preventing runaway operations in devices utilizing microcontrollers or DSPs.
Key electrical specifications include a RESET power supply voltage range of 1.0V to 10V and a WDT power supply voltage range of 2.5V to 10V. The IC boasts a high precision detection voltage accuracy of ±1.5% at 25°C, extending to ±2.5% across its operating temperature range of -40°C to +105°C. It also features a super-low current consumption of typically 5µA.
The reset delay time and watchdog timer monitor time can be set using external capacitance connected to the CT and CTW pins, respectively. The output circuit type is N-Channel Open Drain. This component is suitable for a wide range of electronic devices, including vehicle equipment, displays, servers, DVD players, and telephone systems.
The BD87A29FVM-TR is available in an 8-MSOP package with dimensions of 2.90mm x 4.00mm x 0.90mm. It is supplied on tape and reel.
