PS12
Overview
Many systems require that their power supplies are enabled and disabled sequentially in order to reduce transient current demand on the power bus, or to avoid damage to components having multiple supply voltages such as microprocessors, ASICs, MEMS drivers, etc. The PS12 incorporates a power-up delay timer, a window voltage comparator, 4 open drain enable outputs, and 6 enable delay timers.
- Power supply sequencer with four outputs
- Power-up and power-down sequencing
- Six programmable delays
- Maximum 90V supply voltage
- Input voltage window comparator
- Low power supply current (500µA typical)
- 16-Lead SOIC Package
