FUNCTIONAL DESCRIPTION
(continued)
Control inputs (EN, DIR, PWM)
The cmos level inputs drive the device as shown in fig.4 and described in the truth table.
The device is activated with enable input HIGH signal. For enable input floating (not connected) or VEN=0V the
device is in standby mode. When activating the device a wake-up time of 50μs is recommended to stabilize the
internal supplies.
The DIR and PWM inputs control the driver of the external H-Bridge transistors. The motor direction can be
choosen with the DIR input, the duty cycle and frequency with the PWM input. Unconnected inputs are defined
by internal pull up resistors. During wake-up and braking and before disactivating the IC via enable both inputs
should be driven HIGH.
Truth table:
Symbols: x Don't care
0: Logic LOW or not active
1: Logic HIGH or active
R:Resistive output
L: Output in sink condition
H: Output in source condition
T: Tristate
TS:Thermal shutdown
OV:Overvoltage
UV:Undervoltage
SC:Short Circuit
6. Only those external MOS transistors of the H-Bridge which are in short circuit condition are switched off. All others remain driven
by DIR and PWM.
Thermal shutdown
When the junction temperature exceeds T
JSD
all driver are switched in sink condition (L), the K- output is off and
the diagnostic DG is LOW until the junction temperature drops below T
JSD
- T
JHYST
.
Overvoltage Shutdown
When the supply voltage V
VS
exceeds the overvoltage threshold V
VSOVH
all driver are switched in sink condi-
tion (L), the K- output is off and the diagnostic DG is LOW.
