Motor driver ICs
BA6871BS
Operation notes
The BA6871BS has two thermal shutdown circuits
(TSD1 and TSD2) to protect the IC. The typical shutdown
temperatures are 175 C for TSD1 and 215 C for TSD 2.
When the TSD1 is activated at an elevated chip tempera-
ture, the output pins (pins 1, 3, and 30) are set to the open
state. TSD1 is functional against excessive power dis-
sipation, output short-circuiting, and other irregularities in
the output current, but does not work against overheating
caused by high internal currents due to externally caused
IC damage or pin-to-pin short-circuiting.
When TSD2 is activated at a higher chip temperature, the
high- and low-side output transistors are turned on, and
the internal resistance between the motor power supply
pin (pin 2) and the output ground pin (31 pin) drops to less
than 3
. The motor power supply current (I
M
) is then giv-
en by
V

where
I
M

V

R

is the motor power supply output resistance,
R

is the pin-31 resistance.
In your application, make sure to connect between the
motor power supply and pin 2 a circuit breaker that oper-
ates at currents less than I
M
.
