An apparatus includes an enable circuit having a first input configured to receive a serial data in (SDI) signal, a second input configured to receive a not chip select (nCS) signal, a third input configured to receive a hold (HLD) signal, and an output configured to generate an internal enable signal for controlling a power-up process and a power-down process of an integrated circuit, and a digital core circuit configured to generate the HLD signal after the integrated circuit is powered up by the SDI signal and the nCS signal.

Integrated circuit control apparatus and method

A grounding system includes a first circuit portion and a second circuit portion. The first circuit portion is connected to an input voltage bus and has a terminal being a first ground. The second circuit portion is connected between the first ground and a second ground, and includes a switch branch and a resistor branch. When the positive terminal of a power supply is connected to the input voltage bus and the negative terminal of the power supply is connected to the second ground, the switch branch establishes a first current path between the first ground and the second ground and shorts a first diode in the switch branch. When the positive terminal is connected to the second ground and the negative terminal is connected to the input voltage bus, the switch branch disconnects the first current path and stops shorting the first diode.
