Procurement Notes
Verify the specific suffix TDZ0ATL against the manufacturer's latest datasheet to confirm pinout and functional compatibility. Ensure the ordering information matches the required tape-and-reel packaging format. Cross-reference the part number with official ROHM documentation to validate the exact electrical characteristics and operating conditions before integration into final designs.
Selection Notes
Select this component when designing systems requiring integrated protection for single-cell lithium-ion batteries. It is suitable for applications needing both safety monitoring and a stable low-current power supply rail. Consider the TSSOP-20 footprint and thermal requirements during PCB layout. Verify that the 10 mA output current meets the auxiliary load demands of the target system.
