Product details

Haptics and touch controller with 16 KB Flash

The Texas Instruments MSP430TCH5ERHBT is a dedicated haptics and capacitive touch controller from the TCH5E series, built on the MSP430 core.

NRND — plan a replacement path

For new designs, look at TI's current-generation MSP430 capacitive-touch controllers; the exact recommended replacement is not published in this record, so verify pin-compatibility and memory footprint against your firmware image before committing a BOM change.

Interface set and I/O count

The LIN interface is a plus for automotive haptic feedback modules (steering-wheel switches, touch sliders) where the controller sits on a LIN bus.

The exposed pad is also the primary thermal path — without it, continuous haptic drive at high duty cycles can push the junction above 85°C in a still-air enclosure.

Frequently asked questions

Is MSP430TCH5ERHBT obsolete or NRND?

It is not yet discontinued, but TI advises against using it in new product designs. Existing production can continue, but plan a migration to a current-generation part.

What is the recommended replacement for MSP430TCH5ERHBT?

This record does not list an official TI replacement. For a pin-compatible alternative within the MSP430 touch controller family, compare the memory and peripheral set of current MSP430FR or MSP430G2xx touch parts against your firmware requirements. A direct cross-reference is not published here.
