Power-Supply Tracker controls up to 4 supplies.
Available in 24-pin SSOP and 24-lead DFN packages, LTC2925 power-supply tracking controller provides power-up and power-down profiles for systems with up to 4 supplies. By configuring resistors, IC ramps supplies up and down together with voltage offsets, time delays, or different ramp rates. Power-up timeout circuitry turns off supplies if external voltage monitor fails to indicate that all...
