Description

The 2SK2662 is a 500V N-channel enhancement-mode MOSFET designed for high-voltage switching applications, typically housed in a TO-220 package. It features low on-resistance, high forward transfer admittance, and low leakage current, enabling efficient power handling and fast switching performance. This device is widely used in DC-DC converters, motor drives, and relay control circuits.

  • High forward transfer admittance |Yfs|=4.0S (typ.)
  • Low leakage current with IDSS=100µA (max)
  • High voltage capability up to 500V
  • Enhancement mode operation with Vth=2.0–4.0V
  • Suitable for high-efficiency switching applications

Absolute Maximum Ratings (Tc = 25 °C)

Parameter Symbol Value Unit
Drain-Source Voltage VDSS 500 V
Gate-Source Voltage VGSS ±30 V

Description

The Microchip Technology, ENC28J60 is a standalone Ethernet controller with an industry standard Serial Peripheral Interface (SPI). It is designed to serve as an Ethernet network interface for any microcontroller equipped with SPI. The ENC28J60 meets all of the specifications for IEEE 802.3. It incorporates a number of packet filtering schemes to limit incoming packets. It also provides internal DMA for fast data throughput and support for hardware assisted IP checksum calculation.

2. Integrated MAC and 10BASE-T PHY

3. 8-Kbyte Transmit/Receive Packet Dual Port Buffer SRAM

4. Receiver and Collision Squelch Circuit

5. Supports one 10BASE-T Port with Automatic Polarity Detection and Correction

6. Programmable Automatic Retransmit on Collision

7. Programmable Padding and CRC Generation

8. Programmable Automatic Rejection of Erroneous Packets

9. 10 Mbit/s SPI Interface

Oscillator Start-up Timer

The ENC28J60 contains an Oscillator Start-up Timer (OST) to ensure that the oscillator and integrated PHY have stabilized before use. The OST does not expire until 7500 OSC1 clock cycles (300 μs) pass after Power-on Reset or wake-up from Power-Down mode occurs. During the delay, all Ethernet registers and buffer memory may still be read and written to through the SPI bus. However, software should not attempt to transmit any packets (set ECON1.TXRTS), enable reception of packets (set ECON1.RXEN) or access any MAC, MII or PHY registers during this period.

When the OST expires, the CLKRDY bit in the ESTAT register will be set. The application software should poll this bit as necessary to determine when normal device operation can begin.

LED Configuration

The LEDA and LEDB pins support automatic polarity detection on Reset. The LEDs can be connected such that the pin must source current to turn the LED on, or alternately connected such that the pin must sink current  to turn the LED on. Upon system Reset, the ENC28J60 will detect how the LED is connected and begin driving the LED to the default state configured by the PHLCON register. If the LED polarity is changed while the ENC28J60 is operating, the new polarity will not be detected until the next system Reset occurs.
