- Integrated power-on reset generator eliminates external RC circuits and ensures clean system startup
- Single-channel monitoring in a compact 8-pin SOIC package minimizes board space in space-constrained designs
- Wide operating temperature range and plastic/epoxy construction suit industrial and automotive-adjacent applications
Applications
The TL7705BQDR is used in microcontroller-based systems, embedded controllers, and DSP boards where reliable power-on reset and voltage supervision are critical for safe operation. It protects against processor lockup caused by supply voltage droops or brown-out conditions by asserting a reset signal until the supply stabilizes above the programmed threshold. Its adjustable threshold and compact footprint also make it suitable for battery-powered devices and industrial control equipment with tight space and power budgets.

Frequently Asked Questions
What is the function of the TL7705BQDR?
The TL7705BQDR is a voltage supervisor and reset IC that monitors a power supply and asserts a reset output when the supply voltage drops below an adjustable threshold, preventing erratic microcontroller operation.
Can the reset threshold voltage be adjusted on the TL7705BQDR?
Yes, the TL7705BQDR features an adjustable threshold, allowing designers to set the precise supply voltage level that triggers a reset using an external resistor divider network on the sense input pin.
What package does the TL7705BQDR use?
The TL7705BQDR is packaged in an 8-pin SOIC (Small Outline Integrated Circuit) with JESD-30 code R-PDSO-G8, using plastic/epoxy body material for standard surface-mount PCB assembly.
Does the TL7705BQDR include a power-on reset function?
Yes, it integrates a power-on reset generator that automatically asserts the reset output during power-up, ensuring the system remains in reset until the supply voltage reaches the programmed operating level.
Is the TL7705BQDR RoHS and lead-free compliant?
Yes, the TL7705BQDR has Pb-free code 'Yes' and JESD-609 code e4, confirming full RoHS compliance and lead-free manufacturing, making it suitable for use in environmentally regulated consumer and industrial products.
