摘要： A temperature detection circuit includes a sensor, an integrated circuit (IC) chip, and a resistor. The sensor is operable for sensing a temperature. The IC chip can compare a sense voltage indicative of the temperature with a threshold voltage indicative of a temperature threshold to determine a temperature condition. The IC chip has a substantially constant parameter. The resistor is externally coupled to the IC chip. The IC chip maintains a current ratio, including a ratio of a first current flowing through the sensor to a second current flowing through the resistor, equal to the substantially constant parameter.

摘要： A charging circuit includes an N-channel metal-oxide-semiconductor field-effect transistor (NMOSFET) that controls a charging current to a battery, a charge pump that generates a driving signal based on a plurality of pulses, and a resistor coupled to a gate of the NMOSFE. The resistor and a capacitance of the gate of the NMOSFET form a low pass filter. The driving signal is filtered by the low pass filter to control a gate voltage of the NMOSFET. A variation of a gate-source voltage of the NMOSFET is proportional to a pulse density of the plurality of pulses. A variation of the charging current flowing through the NMOSFET to the battery is proportional to the pulse density.

The driver can generate a pulse signal in a first operating mode and generate a first signal in a second operating mode to control the current through the battery. The filter can filter the pulse signal to provide a filtered DC signal to adjust an on-resistance of a switch in series with the battery based on a duty cycle of the pulse signal in the first operating mode. The filter can receive the first signal and provide a second signal to drive the switch in a linear region in the second operating mode.
