Description
This document is the entry point to the reference documentation of PTC heater discrete IGBT driver board evaluation platform, version 1.0.1.The evaluation platform is for thermal performance evaluation that provides developers with the tools and test data needed to build applications that drive PTC based on high current isolated driver and IGBT from On Semiconductor.This documentation focuses on the output voltage and current adjustment through high side and low side IGBT, and would help user to setup different variables, such as voltage, to get the wanted current and get the wanted test condition. Finally, it will help customer better understand isolated driver and IGBT performance by tested data and curve.
Features
- Peak Current Mode Control with Internal Slope Compensation
- 1.2 V ±2% Reference voltage
- Fixed Frequency Operation
- Wide Input Voltage Range of 3.2 V to 40 Vdc, 45 V Load Dump

- Internal Soft−Start
- Low Quiescent Current in Sleep Mode
- Cycle−by−Cycle Current Limit Protection
- Hiccup−Mode Overcurrent Protection (OCP)
- Hiccup−Mode Short−Circuit Protection (SCP)
- Thermal Shutdown (TSD)
- NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable
- This is a Pb−Free Device
Typical applications
- PTC heater / /Auto / Industry
