PT5126A
1CH DC Motor Driver
DESCRIPTION
FEATURES
The PT5126A is 1 Full-On Drive H-Bridge channel with
two different packages. The driver features wide range
operating from 2V to 24V and low power consumption
by fast switching speed.
 It is low consumption by BCD process adoption
 Two different small packages: ESOP8, SOP8
 Wide power-supply voltage range:
- Control (VCC): 2.7V ~ 5.5V
- Motor (VM): 2.0V ~ 24V
 High DC output current: Max.=2.8A
 Ultra low RDSON(TOP+BOT):
[email protected]°C, 1A for ESOP8;
[email protected]°C, 1A for SOP8
 Low current consumption when power-down:
<0.05μA @25°C
 PWM control, Max. input frequency: 200KHz.
 Operating temperature range: -30 ~ +85°C
 Charge-pump less
 Shoot-through current protection
 Built-in protection circuits
- Under voltage lock out
 - Thermal shut down
