EEDEHD Medium-Power 4+ Inductive Loads Driver IC

Introduction

The objective of this article is to find an IC which can switch 4+ of medium-power inductive loads.

Loads may be stepper motors, DC motors, or solenoids, at user's discretion.

The IC must have the following features:

4+ of independent half-bridge outputs, preferably at least two splittable full bridges / four independent half bridges in same package.

ALL outputs MUST not modify or invert logic of inputs, for any combination of inputs. See issues with motor control ICs with "brake" function.

100mA minimum drive capability per output channel, 0.5A+ desired.

5V-12V+ load side supply voltage.

Relay coil PWM throttle NOT used (for general adaptivity for any loads such as motors, not just relays).

Reasonably protected output stage for inductive loads drive capability.

Reasonably protected output stage for typical failure scenarios (short circuit, overcurrent, overvoltage, undervoltage, overtemperature, etc).

Can keep up with reasonable PWM waveforms and frequencies.

Not a package I hate (FN, BGA, etc).

A package which can dissipate realistic amount of waste heat with REAL loads being switched at reasonable speeds.

High-side switches NOT NMOS (as this requires costly, limited, and noisy charge pump circuitry inside the IC or external to it).

Surface-mount.

Affordable.

Half Bridge (4):

After L298 is disqualified for being too expensive and outdated, NO ICs remain! WTF???

TODO parse this category for just two half-bridge drivers...

TODO DOC WTF ONSEMI DATASHEETS LINKS FROM DK ARE NOT WORKING???
