PT5129
2CH H-Bridge Driver
DESCRIPTION
FEATURES
The PT5129 motor driver provides 2 Full-On Driver
H-Bridge channels. This driver features wide range
operating from 2.0V and low power consumption by
fast switching speed in a compact surface mount
package.
 Range of motor power supply voltage:
-Control (VCC): 2.5V to 5.5V
- Motor (VM): 2.0V to 16V
 High DC output current: Max.=1.8A
 Ultra low RDSON(TOP+BOT): [email protected]°C
 Charge pump-less type with p-channel DMOS for
the upper side transistor
 Low current consumption when power-down: <1μA
@25°C
 High-speed switching:
-Turn On Time: 350ns, Turn Off Time: 125ns (Typ.)
 Operating temperature range: -30℃ to +85℃
 Built-in protection circuits
- Under Voltage Lock Out (UVLO)
- Thermal Shut Down (TSD)
APPLICATIONS
 Single-lens reflex
 Mobile system
 Home appliance
 Amusement system

APPLICATION CIRCUIT
Note: VM pin groups 9, 10 and 21, 22 are recommended to be short-circuited on the PCB pattern. If cannot,check into transitional characteristics of
total application circuit including two motors. Through low impedance materials, the possibility of causing some unexpected malfunctions is
incontrovertible.
