Patent number: 8482324Abstract: A circuit includes an ATX power connector with a PSON pin, a time delay circuit, and a stabilizer circuit. The time delay circuit receives an input PSON# signal and then sends an output PSON# signal to the PSON pin of the power connector after a time delay has elapsed. The stabilizer circuit is coupled to the PSON pin of the power connector for stabilizing the output PSON# signal.Type: GrantFiled: August 7, 2009Date of Patent: July 9, 2013Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventor: Qi-Jie Chen

Patent number: 8201003Abstract: A circuit for confirming a correct computer power down sequence includes a Southbridge chip, a first switching transistor circuit, and a second switching transistor circuit. The first switching transistor circuit receives a power good signal. The second switching transistor circuit receives a S3 sleep signal. The first and second switching transistor circuits have a common output node coupled to the Southbridge chip. During a computer power down sequence, the S3 sleep signal is set from high to low before than the power good signal, and the S3 sleep signal is active and fed to the Southbridge chip, thereby quickly providing a low level power good signal to the Southbridge chip and confirming the power down sequence is correct.Type: GrantFiled: September 10, 2009Date of Patent: June 12, 2012Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventor: Qi-Jie Chen

Patent number: 8166329Abstract: A circuit for a computer system, includes a pulse width module (PWM) module and a control circuit. The PWM module is capable of converting a first voltage to a second voltage. The first voltage is capable of decreasing slower than the second voltage to have the PWM module entering in an unwanted state when the computer system is changed from a first state to a second state. The PWM module includes a disabling pin capable of locking the PWM module when a voltage of the disabling pin is low. The control circuit includes a control pin connected to the disabling pin, a ground pin connected to ground, and a monitoring pin capable of monitoring the computer system being changed from a first state to a second state to control the control pin and the ground pin to pull the disabling pin low to lock the PWM module to prevent the PWM module from entering in the unwanted state.Type: GrantFiled: July 23, 2009Date of Patent: April 24, 2012Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventor: Qi-Jie Chen
