BD9555FVM-CGTR

Programmable Timers And Oscillators Overview

The BD9555FVM-CGTR is a CR Timer IC manufactured by ROHM Semiconductor, designed for timing applications within automotive and industrial environments. It operates on a single power supply ranging from 4.5 V to 42 V. The device integrates one timer channel capable of generating frequencies between 1 Hz and 10 kHz. Electrical characteristics include a high-level output current of 10 mA and a low-level output current of 50 mA, with an operating supply current of 1 mA. It features no shutdown function and dissipates up to 380 mW. The component is qualified under AEC-Q100 standards and functions reliably across a temperature range of -40°C to +125°C.

Programmable Timers And Oscillators Feature Summary

• AEC-Q100 qualified for automotive reliability
• Wide supply voltage range: 4.5 V to 42 V
• Single-channel CR timer operation
• Output drive capability: 10 mA (high) / 50 mA (low)

Programmable Timers And Oscillators Applications

• Automotive timing control circuits
• Industrial delay generation systems
• General-purpose timer modules requiring wide voltage tolerance

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix CGTR indicates the reel packaging format containing 3000 units per factory pack. Confirm RoHS compliance status through official documentation before integration. Ensure the MSOP-8 package dimensions align with PCB layout requirements. Check for any Product Change Notices (PCN) that may affect mechanical or material specifications while maintaining electrical performance consistency.

Programmable Timers And Oscillators Selection Notes

Select this component when a single timer channel is sufficient for the design. The 42 V maximum input voltage allows direct connection to higher voltage automotive buses without additional step-down regulation for the supply rail. Consider the 1 mA operating current for power-sensitive designs. The absence of a shutdown pin simplifies circuit topology if external control of the timer state is not required.

Programmable Timers And Oscillators Part Context

This part belongs to ROHM's Timer & Support Products category, specifically under Clock & Timer ICs. It is distinct from other BD-series components like the BD1HD500FVM (High Side Switch) or BD6981FVM (Motor Driver). The FVM suffix denotes the MSOP-8 package type, while CGTR specifies the tape and reel shipping configuration.

Programmable Timers And Oscillators Replacement Considerations

No public confirmed substitute part numbers are available in the provided data. Direct replacements must be sourced from ROHM's current portfolio or verified equivalents with matching CR timer functionality, voltage range, and AEC-Q100 qualification.
