Key Features
- Dual-channel architecture monitors two independent power supply rails simultaneously with adjustable voltage thresholds for flexible system supervision
- Integrated power-on reset generator ensures microprocessors and digital systems start up cleanly after power cycling or brownout events
- Adjustable threshold detection allows designers to set custom supervision levels for non-standard supply voltages in diverse system designs
Applications
The TL7770-5IDWR is ideal for embedded processor supervision, multi-rail power monitoring in industrial controllers, and communication system reset management. Its dual-channel capability allows simultaneous monitoring of two power supplies such as 3.3 V and 5 V rails, generating clean reset signals when either drops below the adjustable threshold. The 16-pin SOIC package facilitates easy surface-mount integration in space-efficient PCB designs.

Frequently Asked Questions
How many voltage channels can the TL7770-5IDWR monitor?
The TL7770-5IDWR monitors 2 independent voltage channels simultaneously. Each channel has an adjustable threshold, allowing the device to supervise two different supply rails such as 3.3 V and 5 V in a single microprocessor or DSP system, simplifying power management design.
Does the TL7770-5IDWR include a power-on reset function?
Yes, the TL7770-5IDWR includes an integrated power-on reset generator that ensures a clean, timed reset signal is generated when the monitored supply voltages rise above their thresholds during power-up. This prevents microprocessors from executing code while supplies are still ramping, enhancing system reliability.
What is the package type and size of the TL7770-5IDWR?
The TL7770-5IDWR is housed in a 16-pin small outline IC (SOIC) package with JESD-30 code R-PDSO-G16 and plastic/epoxy body material. This standard surface-mount package makes it easy to integrate into compact PCB designs for industrial, automotive, and consumer electronics applications.
Can the threshold voltage of the TL7770-5IDWR be adjusted?
Yes, the TL7770-5IDWR features adjustable threshold detection on both channels. External resistor dividers allow designers to program the exact undervoltage trip points for each monitored rail, making the device flexible for non-standard supply voltages and custom supervision requirements across a wide range of embedded system designs.
