Overview
The ZNBG3115Q20TC is a Bias Controller PMIC from Diodes Incorporated, designed for precise voltage and current control. It operates within a supply voltage range of 5V to 10V and draws a supply current of 25mA. The device features an internal 2.2V reference and supports three bias outputs with tone and high/low capabilities. It is housed in a 20-QSOP package (20-SSOP, 3.90mm width) and functions reliably across a temperature range of -40°C to 70°C.
Feature Summary
- Integrated bias controller for precise power management
- Supports multiple bias outputs with tone and polarity options
- Compact surface-mount packaging for space-constrained designs
Applications
- Display panel bias generation
- LCD driver power sequencing
- Portable electronic device power management
Procurement Notes
Verify component authenticity through authorized Diodes Incorporated distributors or certified partners. Confirm package integrity and pin alignment upon receipt. Check for RoHS3 compliance markings on the reel or tape. Ensure storage conditions maintain moisture sensitivity level 1 standards prior to soldering.
Selection Notes
Evaluate thermal requirements against the -40°C to 70°C operating range. Confirm compatibility with 5V–10V supply rails. Assess PCB layout constraints for the 20-QSOP footprint. Verify that the 25mA supply current meets system power budgets. Consider obsolescence status when planning long-term production cycles.
Part Context
This component belongs to the ZNBG series of bias controllers from Diodes Incorporated. It complements related models like the ZNBG3211Q20TC, offering specialized power management solutions for display and portable electronics. The series focuses on integrated bias generation with compact form factors.
Replacement Considerations
Public confirmed substitute part numbers are not available. The ZNBG3115Q20TC is listed as obsolete/inactive. Designers should consult Diodes Incorporated for current alternatives or evaluate cross-reference options based on functional equivalence.
