Description
The uP7534 is a current limited high-side switch designed for applications where heavy capacitive loads and shortcircuits are likely to be met. This device operates with inputs from 2.7V to 5.5V for both 3V and 5V systems. Its low quiescent current (25uA) and standby current (<1uA) conserve battery power in portable. The power switch is controlled by a logic enable input and driven by an internal charge pump circuit.
The uP7534 features glitch-blank fault flag that is asserted by overcurrent, overtemperature, or input undervoltage lockout. The 8ms glitch-blanking time allows momentary faults to be ignored, thus preventing false alarms to the host system.
