Introduction
The KIT33816AEEVM
Evaluation Board (EVB) is an easy-to-use circuit board that allows the user to
exercise all the functions of the MC33816 Smart Pre-driver circuit. A PC communicates to the EVB
through a USB/SPI dongle (KITUSBSPIDGLEVME) connected to the PC’s USB port. The Freescale
SPIGen (version 7.0 and above) program provides the user interface to the MC33816 SPI port and allows
the user to program the Code RAM and Data Registers, send commands to the IC and receive status
from the IC.

MC33816 Device Features
•
Battery voltage range, 5.5 V < V
BATT
< 32 V
(1)
•
Pre-drive operating voltage up to 72 V
•
High-side/ low-side pre-drive PWM capability up to 100 kHz
•
All pre-drivers with four selectable slew rates
•
Eight selectable, pre-defined VDS monitoring thresholds

Freescale analog ICs are manufactured using the SMARTMOS process, a combinational BiCMOS
manufacturing flow that integrates precision analog, power functions and dense CMOS logic together on
a single cost-effective die.
Notes
1. In case V
SUPP
> 16 V, it is highly recommended to disable the internal V
CCP
regulator and externally supply V
