Product details

1.1 A per half-bridge — sizing the motor load

The TC78H611FNG,EL is a DMOS motor driver from Toshiba that integrates two half-bridges, each rated for 1.1 A continuous output. That current drives small brushed DC motors or one bipolar stepper motor in general-purpose applications like office automation, vending machines, or small pumps. The PWM interface accepts standard logic-level signals from a microcontroller, so speed and position control are handled in firmware without an external DAC.

Load voltage range — 2.5 V to 15 V

The motor supply spans 2.5 V to 15 V. It works with 5 V MCUs on the control side.

Package and rework — 16-TSSOP

The 16-TSSOP package (4.40 mm width, 0.173" pitch) is a fine-pitch surface-mount part. It reflows cleanly with standard lead-free profiles.

Temperature grade and environment

Not specified for automotive under-hood or extended outdoor enclosures. The DMOS output stage handles the current with low RDS(on).

Lifecycle and sourcing

It is ROHS3 compliant.

Frequently asked questions

Is TC78H611FNG compatible with 5V microcontrollers?

Yes.

What is the difference between TC78H611FNG and TB6600HG?

The TB6600HG is a higher-current stepper driver (4.5 A) in a through-hole package with parallel interface, intended for larger motors. The TC78H611FNG,EL is a lower-current (1.1 A) surface-mount driver with PWM interface, suited for smaller brushed DC or bipolar stepper motors. They are not pin-compatible; the TC78H611FNG,EL is the smaller, surface-mount option for space-constrained designs.
