Thermal Design
1. Heat Sink Thermal Resistance (
θ
c-a) Derivation
The size of the heat sink required for the hybrid IC is determined by the motor output current (I
OH
), the electrical
characteristics of the motor and the chopping frequency, and the frequency of current application.
The thermal resistance (
θ
c-a) of the heat sink is derived from the following formula.
θ
c-a =Tc max – Ta
(°C/W)
Pd
Tc max: Hybrid IC case temperature (°C)
Ta:
Ambient temperature within the set (°C)
Pd:
Average internal power dissipation within the hybrid IC (W)
As an example, Figure 2 can be used to derive the required area for a 2 mm aluminum plate heat sink. Since the ambient
temperature within a set varies greatly with the set internal air circulation conditions, the size of the heat sink must be
determined taking into account the constraint that the temperature of the back surface of the IC (the aluminum plate side)
must never under any conditions exceed 105°C.
No. 4874-3/8
STK6877
H: 5 V
L: 0 V
Note: 1. Input pin specifications
TTL levels handled
Maximum PWM input frequency: 30 kHz
When used in two pin control mode, the PWM pin must be tied high.
2. Since the OSC pin (pin 11) is a monitor pin, it should be left open in normal operation.
