The three half-bridge drivers are capable of delivering a peak output current of 0.
5A at 12V for driving high-side and low-side NMOS MOSFET transistors.
The drivers have shootthrough, overcurrent and short-circuit protection.
A Sleep mode has been added to achieve a typical “key off” quiescent current of 5 µA.
The MCP8021/2 devices integrate a 3.
3V or 5.
0V LDO regulator for host and peripheral power, an overtemperature sensor and user-configurable functi...
