TC78S121FNG
TOSHIBA CD Process Integrated Circuit Silicon Monolithic
TC78S121FNG
PWM Chopper Type Dual-Stepping Motor Driver
The TC78S121FNG is a PWM chopper type dual-stepping motor driver.
Two stepping motor drivers can drive up to four brushed DC
motors. Incorporating two pairs of H-bridge drivers, the
TC78S121FNG can drive two DC motors or a single stepping
motor.
Features
Single-chip motor driver for bipolar stepping motor
control
Monolithic IC structured by CD process.
Low ON-resistance: R
on
= 0.6 Ω
In large mode, ON-resistance of combined H-bridges (R
on
) is 0.3 Ω.
HTSSOP48-P-300-0.50
Weight: 0.212 (g)
Over-current detection (ISD), thermal shutdown (TSD) and V
M
power-on reset circuits
Since the IC incorporates the V
CC
regulator for internal circuit operation, an external power supply (5 V)
is not required.
Package: HTSSOP48-P-300-0.50 0.5 mm pitch
Maximum output withstand voltage: 40 V (max)
Output current: 2.0 A (max) in DC Motor (S) mode; 1.5 A (max) in Stepping Motor (S) mode
Chopping frequency can be set by external capacitor and resistor. High-speed chopping is possible at
100 kHz or higher.

Why does STM32 stop running after a period of time?
I have a board that works fine, but after using it for a while (about 1 month), I found that it can no longer run, because I didn't use JTAG. I only did a method to light up the LED before the system ...
