Note 1: Thermal shut down (TSD) circuit
When the IC junction temperature reaches the specified value and the TSD circuit is activated, the internal
reset circuit is activated switching the outputs of both motors to off.
When the temperature is set between 130 (min) to 170°C (max), the TSD circuit operates. When the TSD
circuit is activated, the function data latched at that time are cleared. Output is halted until the reset is
released. While the TSD circuit is in operation, the charge pump is halted.
Even if the TSD circuit is activated and
RESET
goes H
→
L
→
H instantaneously, the IC is not reset until
the IC junction temperature drops 35°C (typ.) below the TSD operating temperature (hysteresis function).
Note 2: Overcurrent protection circuit
When current exceeding the specified value flows to the output, the internal reset circuit is activated
switching the outputs of both shafts to off.
When the ISD circuit is activated, the function data latched at that time are cleared.
Until the
RESET
signal is input, the overcurrent protection circuit remains activated.
During ISD, the charge pump halts.
For failsafe operation, be sure to add a fuse to the power supply.
