IR2136PBF - Infineon

IR2136PBF Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the IR2136PBF?
  The maximum operating frequency of the IR2136PBF is 600 kHz, but it can be adjusted up to 1 MHz with an external oscillator.
• How do I configure the deadtime between the high-side and low-side switches?
  The deadtime can be configured using the DT pin, which sets the deadtime between the high-side and low-side switches. A longer deadtime can be achieved by connecting a capacitor between the DT pin and ground.
• What is the purpose of the SD pin, and how do I use it?
  The SD pin is a shutdown input that allows the user to disable the device. When the SD pin is pulled low, the device enters a low-power shutdown mode, reducing the quiescent current to less than 10 μA.
• How do I protect the IR2136PBF from overcurrent and overvoltage conditions?
  The IR2136PBF has built-in overcurrent protection (OCP) and overvoltage protection (OVP) features. The OCP threshold can be set using an external resistor, and the OVP threshold is fixed at 18 V. Additionally, the device has a thermal shutdown feature that disables the device if the junction temperature exceeds 150°C.
• What is the recommended layout and PCB design considerations for the IR2136PBF?
  The IR2136PBF requires a careful PCB design to minimize electromagnetic interference (EMI) and ensure reliable operation. It is recommended to use a multilayer PCB with a solid ground plane, and to keep the high-current paths short and wide. Additionally, the device should be placed close to the power MOSFETs, and the bootstrap capacitor should be placed close to the device.
