VIPower M0-5 and M0-5Enhanced
high-side drivers
Introduction
The aim of this document is to give the design engineer a comprehensive “tool kit” to better
understand the behavior of VIPower high side switches, allowing easier design and saving
time and money.
Today’s VIPower high side switches represent the 5th generation of smart power drivers (the
so called M0-5). In this latest generation of drivers, all the experience and know-how derived
from previous generations have been implemented in order to improve robustness, increase
functionality and raise package density while maintaining lower prices.
The complexity of a modern High Side Driver (HSD) is still relatively low compared to many
other logic ICs. However, the combination of digital logic functions with analog power
structures supplied by an unstabilized automotive battery system across a wide temperature
range is very challenging for such a device.
The M0-5 components today meet all the above criteria, providing an optimal
price/performance ratio by offering the highest performance and robustness at excellent
prices.

1. If status disable function is not required, ST_DIS pin should be left open or connected to ground through a
resistor (~10 kΩ). Direct connection to ground is not safe (ISO pulses clamped through ST_DIS pin can
damage the device).
2. Pull-up R5 is optional (for open load detection in off-state).
3. No pull-down resistors are necessary on IN and ST_DIS pins due to the internal pull-down structure.
