the signals at the VU and VL pins; this ensures the complete
turn-off of any transistor before turning on its associated in-line
transistor.
CHARGE PUMP
The PWR-82330 has an internal charge pump circuit to generate
the drive voltage for the high side N-channel MOSFETs. The
charge pump uses an oscillator to charge an external charge pump
capacitor, Cc, from the Vcc supply. This oscillator will pump the
voltage at pin 48 (+cap) of the hybrid higher than Vcc. The hybrid
high side drivers use this voltage to ensure the proper gate drive.
An external 1 F, 20% capacitor (Cc) is required between pins 48
and 50. If a polarized capacitor is used, the positive terminal
must be connected to pin 48. The voltage rating of Cc must be
2x the maximum value of VCC.

PWR-82330 POWER DISSIPATION (SEE FIGURE 7)
There are three major contributors to power dissipation in the
motor driver: conduction losses, switching losses, and intrinsic
diode losses.
VCC = +28 V (Bus Voltage)
IoA = 3 A, IOB = 7 A (see FIGURE 7)
ton = 20 s, T = 40 s (period) (see FIGURE 7)
Ron = 0.13
Ω (on-resistance, see TABLE 2, Io = 5 A, Tc=+25°C)
ts1 = 325 ns, ts2 = 325 ns (see FIGURE 7)
fo = 25 kHz (switching frequency)
VF is an intrinsic diode forward voltage, TABLE 2, Io = 5 A
1. Conduction Losses (PC)
Pc = ( Imotor rms)2 x Ron
Pc = (3.63 A)2 x (0.13 W)
Pc = 1.71 Watts
2. Switching Losses (Ps)
Ps = [ Vcc ( IOA (ts1) + IOB (ts2) ) fo] / 2
Ps = [ 28 V ( 3 A (325 ns) + 7 A (325 ns) ) 25 kHz] / 2
Ps = 1.14 Watts
