DESCRIPTION
The PT5126 is 1 Full-On Drive H-Bridge channel with
three different packages. The driver features wide
range operating from 2V to 24V and low power
consumption by fast switching speed.
FEATURES
PWM control, Max. input frequency: 200KHz.
Operating temperature range: -30 to +85°C
Charge-pump less
Shoot-through current protection
Built-in protection circuits
- Under Voltage Lock Out
- Thermal Shut Down
APPLICATION
 It is low consumption by BCD process adoption
 Three different small packages: QFN16(3x3),
TSSOP14, ESOP8
 Wide power-supply voltage range:
- Logic (VIO): 1.62V to VCC
-Control (VCC): 2.7V to 5.5V
- Motor (VM): 2.0V~24V
 High DC output current: Max.=1.8A
 Ultra low RDSON(TOP+BOT):
[email protected]°C, 1A
 Low current consumption when power-down:
<1μA @25°C
 Lens for DSLR
 Auto icemaker or dumper drive for refrigerator
 HV bi-direction DC Motor
