A thermal protection circuitry turns off all drivers when
the junction temperature exceeds a safe operating limit
of 170°C (typ.). This protects the devices from failure
due to excessive heating. Despite this thermal protec-
tion, output short circuits are not permitted. The output
drivers are re-enabled once junction temperature has
dropped below 145°C (typ.).

vs. Temperature Showing Hysteresis
An undervoltage lockout circuit protects the MTS2916A
from potential shoot-through currents when the load
supply voltage is applied prior to the logic supply volt-
age. The power bridge and all outputs are disabled if
VLOGIC is smaller than 4V.
With this protection feature, the circuit will withstand
any order of turn-on or turn-off of the supply voltages
VLOGIC and VLOAD. Normal dV/dt values are
assumed.
