Quad sequencer IC cascades multiple supplies

Linear Technology’s LTC2924 monitors and enables up to four supplies in sequence during both power-up and power-down, and multiple LTC2924 controllers can be easily cascaded to sequence eight, twelve or a virtually unlimited number of voltages. Tailoring the LTC2924 to a specific application requires no software and designs can be fine-tuned during system integration simply by changing resistor and capacitor values.
