The TPCL4202 (TE85L,F) is a dual N/P-channel MOSFET Array designed for low on-resistance. It is ideal for applications such as load switch, low side switch, load pull-up switch, voltage clamp, and general switching purposes. The device is constructed with a substrate PNP and two complementary N and P-channel MOSFETs.

Pin Configuration and Electrical Characteristics

The TPCL4202 offers a variety of pin configurations and electrical characteristics, depending on the manufacturer. The device is typically available with a drain-source voltage (VDS) of up to 20 volts, a drain-gate voltage (VGS) of up to 5 volts, and a drain-source on-resistance (RDS(on)) of up to 1.5 ohms. This device features a gate charge of up to 0.75 nanocoulombs, a drain-source breakdown voltage of up to 20 volts, and a total gate charge of up to 0.15 nanocoulombs. The device also offers an avalanche energy rating of up to 2.5 watts.

Application Field

The TPCL4202 is widely used in a variety of applications such as load switch, low side switch, load pull-up switch, voltage clamp, and general switching purposes. It is also widely used in battery-powered applications, automotive applications, and portable electronics. In addition, the device is widely used in low power DC/DC converters and AC/DC converters.

Working Principle

The TPCL4202 incorporates two separate MOSFETs, with each MOSFET having its own gate and drain-source terminals. The gate of each MOSFET is connected to the substrate PNP, which controls the biasing of the MOSFETs. When a logic low is applied to the gate of either MOSFET, the PNP conducts and turns on the corresponding MOSFET. When a logic high is applied to the gate of either MOSFET, the PNP is non-conducting, which turns off the corresponding MOSFET.

When the two MOSFETs of the TPCL4202 are switched on or off, the voltage between the drain and source of the device changes. This voltage is proportional to the current flowing through the device and is determined by the gate-to-source voltage (VGS) of the device. The gate-to-source voltage determines the current flow through the device, which in turn determines the voltage at the drain and source terminals.

In addition, the TPCL4202 features an avalanche rating, which is the amount of energy required to break down the junction between the source and drain of the device. This is an important safety feature as it ensures that the device will not fail catastrophically if an excessive voltage or current is applied between the source and drain terminals.

The TPCL4202 is a robust and reliable MOSFET array that can be used in a variety of applications. It is a low on-resistance device, which makes it suitable for battery powered and automotive applications, as well as DC/DC and AC/DC converters.
