Adjustable reset timeout
Simultaneous monitoring of four power supplies
±0.5% reset threshold accuracy
Analog Devices announced on the 6th the launch of the LTC2962-LTC2964 family of 4-channel voltage supervisors.

ASIC, FPGA, DSP, MCU, and MPU architectures that operate on supply voltages as low as 1 V will either eliminate system voltage margin or narrow the remaining load operating voltage range if they use voltage supervisors with a reset threshold accuracy of ±1-2%.

The LTC2962 family significantly reduces power consumption by easing power supply demands and increasing system transient immunity with a ±0.5% reset threshold accuracy. The LTC2962 family's high accuracy, flexible 1V to 5V reset threshold, and wide operating temperature range make it ideal for a wide range of network, telecom, and automotive applications.

The LTC2962 family is a solution for many multi-rail applications in the low power voltage monitoring market. For each channel, you can pre-select one of 16 or easily select adjustable ±0.5% accuracy voltage limits for undervoltage, overvoltage, or negative monitoring.

The supervisor circuit monitors inputs and drives outputs based on configured limits. Alternatively, a manual reset input using a pushbutton switch is also available as an option to reset the system. Options include a watchdog with an adjustable timer (LTC2963-1) and a device with individual comparator open-drain outputs for each channel (LTC2964). Both devices feature adjustable timeout periods.

The LTC2962 family is currently available in multiple temperature grades: C grade (0°C to 70°C), I grade (–40°C to 85°C), and H grade (–40°C to 125°C). The LTC2962 is available in a 16-lead 3mm x 3mm QFN package, while the LTC2963-1 and LTC2964 are available in a 20-lead 3mm x 4mm QFN package.
