The ISL6123, ISL6124, ISL6125, ISL6126, ISL6127, ISL6128 are a four-channel power supply sequencer with supply monitoring, fault protection and a "sequence completed" signal (RESET#).
The document details a family of integrated 4-channel controlled-on/controlled-off power-supply sequencers. These ICs include supply monitoring, fault protection, and a 'sequence completed' signal (RESET#). For systems requiring more than four supplies, multiple units can be cascaded by connecting SYSRESET# pins.
The datasheet covers various models within the ISL612X series, each offering different configurations such as open-drain outputs for direct interface or charge-pump driven gate drive. Features include adjustable voltage slew rates, glitch immunity, and under-voltage lockout for each supply.
| Undervoltage Lockout Threshold Typ | 633 mV |
|---|---|
| Undervoltage Lockout Delay | 10 ms |
| Transient Filter Duration | 30 us |
The typical undervoltage lockout threshold is 633 mV at +25°C.
Yes, more than four supplies can be sequenced by connecting a wire between SYSRESET# pins of cascaded ICs.
