ISL8723
ISL8723 is Power Sequencing Controllers manufactured by Renesas.
Features
- Enables arbitrary turn-on and turn-off sequencing of up to four power supplies (0.7V to 5V)
- Operates from 2.5V to 5V supply voltage
- Supplies VDD +5.3V of charge pumped gate drive
- Adjustable voltage slew rate for each rail
- Multiple sequencers can be easily daisy-chained to sequence an infinite number of independent voltages
- Glitch immunity
- Undervoltage lockout for each monitored supply voltage
- 30µA Sleep State (ISL8723)
- Active high (ISL8723) or low (ISL8724) ENABLE input
- Pb-free (Ro HS pliant)
Applications
- Graphics cards
- FPGA/ASIC/microprocessor/Power PC supply sequencing
- Network Routers
- Telemunications Systems
