[AP1019] 017015009-E-00 2017/12 - 1 - 1. General Description The AP1019 is a dual H-Bridge Motor Driver to operate up to 9.0V power supply. It has four drive modes of operation; Forward, Reverse, Brake and Standby. It is capable to configure the input logic which is suitable for the PWM drive with the SEL terminal. The driver works up to 1MHz, therefore it can suppress the current ripple and reduce the motor sound. The AP1019 has an N-ch LDMOS FET for both high side and low side of the output circuit, realizing to adopt a small WL-CSP package. In addition, the AP1019 has under-voltage detection and thermal shutdown circuits. It is suitable for driving various small motors. 2.

9.2 Protection Functions
- Shoot-through Current Prevention Circuit In order to prevent high side and low side MOSFETs from turning on at the same time, a through current prevention circuit is built in. MOSFETs are turned off for both high side and low side during the dead time period that is when the shoot-through current prevention circuit is in operation. The dead time is included in the H-Bridge output delay time of the electrical characteristics. Figure 5 shows the signal timing images.

- Thermal Shut Down (TSD) The AP1019 prevents damages from self-heating by setting OUTA and OUTB outputs Hi-Z when abnormal high temperature is detected. The AP1019 is able to return to normal operation as soon as the temperature drops to the level lower than the bottom detection threshold.
