FAN3224TMPX

FAN3224TMPX is a Texas Instruments part in the FAN3224 family: a four-channel high-side (load) switch IC in a compact TMPX package. Each channel provides independent switching of a load with built‑in protection and diagnostic features, designed to simplify power distribution in automotive and general power-management designs.
Key points:
- Four independent high-side switches with protection (overcurrent/short to ground, thermal shutdown, undervoltage lockout) and fault reporting.
- Independent INx control pins with a common EN for on/off.
- Optional current-limiting per channel; fast turn-on/off to reduce PWM ripple.
- Package: TMPX (small, suitable for compact layouts).
Benefits:
- Reduces external components, consolidates protection and diagnostics in one IC.
- Improves reliability and fault visibility for multiple loads.
Typical applications: automotive power distribution, LED backlighting, motor/actuator drives, and other multi-load switching in compact boards.
For exact electrical specs (supply range, current limits, pinout, thermal data) consult the TI FAN3224TMPX datasheet.

16-pin surface-mount, TSSOP package (TMPX variant).

Pin count: 16 pins (16‑pin package).
Function: Four‑channel high‑side/low‑side gate driver for driving external N‑channel MOSFETs (HOx/LOx outputs with bootstrap VB/VBS supplies), used for motor control/power switching.

Manufacturer: Fairchild Semiconductor (now part of ON Semiconductor).
What kind of company: A global semiconductor company that designs, manufactures, and sells integrated circuits and related semiconductor products for automotive, consumer, industrial, and computing applications.

Possible application areas for FAN3224TMPX:
- Automotive and industrial control: protected load switches for motors, fans, solenoids
- LED backlight and illumination drivers
- Relays and contactors switching
- Power-supply gating with overcurrent/thermal protection
