 Application IN_A IN_B 0.1μF M LDO 47u~ 220μF 1μF 0R~2R 1uF GND AM1096 LDO VCC IN_B IN_A OUT_A PVCC OUT_B C1C2  Circuit Descriptions 1. The function descriptions of capacitors on the application circuit: C1、C2: Power supply PVCC/VCC pin capacitor: 1) The capacitor can reduce the power spike when the motor is in motion. To avoid the IC directly damaged by the PVCC/VCC peak voltage. It also can stabilize the power supply voltage and reduce its ripples. 2) The C1 capacitor can compensate power when motor starts running. 3) The capacitor value (μF) determines the stability of the P VCC/VCC during motor in motion. In general, 47μF capacitor is enough in low voltage power ( PVCC) , 1μF capacitor is enough in l ow voltage power (V CC). If the large voltage power or a heavy loading motor is used, then a larger capacitor would be needed. 4) On the PCB configuration, the C1、C2 must be mounted as close as possible to V CC/PVCC pin (PIN4/PIN5). C3: The LDO output capacitor 1) The capacitor can reduce the power spike while motor is in motion; it also can stabilize the LDO output voltage and reduce its ripples. C4: The across-output capacitor 2) The capacitors can reduce the power spike of motor when operating. Therefore, a 0.1μF capacitor is recommended. 3) On the PCB configuration, the C4 must be mounted as close as possible to OUT_A&B (PIN 6 & PIN 8). 4) The C4 capacitor must be added to the general application.

If the IC junction temperature falls to 100 ﾟ C(Typ.), the IC resumes automatically. 2) Over-current protection (OCP) While the IC conducts a large current, 2.5 A (Typ), the internal over -current protection function will be triggered. The device enter protection mode of auto-recover to avoid damaging IC and system. AMtek semiconductors Oct . 2016 V0.5 - 7 -
