What are the key features of TL7700CMPWPSEP?
- Radiation hardened design tolerates total ionizing dose (TID) up to 30 krad, suitable for low-Earth orbit and satellite applications
- Adjustable threshold on a single-channel voltage supervisor for flexible supply monitoring down to 1.2 V rails
- Space Enhanced Plastic (SEP) SOIC-8 package balances radiation tolerance with cost-effective PCB assembly
What is TL7700CMPWPSEP used for?
The TL7700CMPWPSEP is used in space-grade and high-reliability electronics where supply voltage supervision is critical. It monitors power rails in satellite subsystems, launch vehicle avionics, and radiation-tolerant industrial control boards, asserting a reset signal within microseconds of an undervoltage event. Its adjustable threshold and single-channel architecture make it straightforward to integrate into compact designs operating in harsh radiation environments.

Frequently Asked Questions
What total ionizing dose (TID) can the TL7700CMPWPSEP withstand in a space radiation environment?
The TL7700CMPWPSEP is characterized to withstand a total ionizing dose of up to 30 krad(Si), making it suitable for low-Earth orbit missions and other radiation-exposed environments where conventional ICs would degrade or fail.
How does the adjustable threshold feature help when monitoring multiple supply voltages in a satellite power system?
Because the threshold is externally adjustable via a resistor divider, designers can set the supervisory trip point anywhere in the supported range to match rails from 1.2 V to 5 V, eliminating the need for separate fixed-threshold supervisors on each rail and saving board space on a 1U CubeSat PCB.
What is the package type and pin count of the TL7700CMPWPSEP, and how does that affect PCB layout?
The device ships in an 8-pin Small Outline (SOIC-8) Space Enhanced Plastic package with a body width of approximately 3.9 mm, allowing a compact footprint. The standard SO-8 land pattern is compatible with most PCB EDA libraries, reducing layout time for high-reliability avionics boards.
When would an engineer select the TL7700CMPWPSEP over a commercial-grade voltage supervisor such as TL7700C?
The TL7700CMPWPSEP adds radiation tolerance up to 30 krad(Si) and is manufactured under the Space Enhanced Plastic program for enhanced reliability screening, whereas the commercial TL7700C is only rated for standard industrial temperature ranges. Engineers select the SEP variant when the end product must meet NASA or ESA radiation requirements without the cost of full military or space-qualified ceramic packaging.
What reset pulse width does the TL7700CMPWPSEP provide when the monitored supply drops below threshold?
The TL7700CMPWPSEP generates a minimum active-low reset pulse of approximately 200 ms when the supervised supply drops below the programmed threshold voltage, giving downstream microcontrollers and FPGAs sufficient time—well over the 1 ms minimum required by most processors—to enter a safe state before power is restored.
