When the default OVP threshold is used, connect OVLO pin to GND directly or through a 0Ω resistor. OVLO pin cannot be left floating. ic 2. If R1 and R2 are used to adjust the OVP threshold, in order to speed up the OVP response, R 1 + R2 < 100kΩ is recommended. It is better to use 1% precision resistors to improve the OVP threshold precision. in 3. If ACOK is not used, it can be left floating, or short to GND. 4. CIN = 0.1μF is recommended for typical application, larger CIN is also acceptable. The rated voltage of CIN should be larger than the TVS maximum clamping voltage, if no TVS is applied and only AW 328XX is used, the rated voltage of CIN should be 50V. w 5. COUT = 1μF is recommended for typical application, larger C OUT is also acceptable. The rated voltage of COUT should be larger than the OVP threshold. For example, if the OVP threshold is 6.8V, the rated voltage of COUT should be 10V or higher. a 6. If the input of AW328XX is required to pass surge voltage greater than 100V, external TVS is needed, the maximum clamping voltage of the TVS should be below 42V. www.awinic.com.cn 4 Copyright © 2014 SHANGHAI AWINIC TECHNOLOGY CO., LTD AW32801/AW32805/ AW32809/AW32812 June 2018 V1.2 Temperature Package Marking Moisture Sensitivity Level Environmental Information Delivery Form AW32801CSR -40°C～85°C WLCSP 1.34×1.78-12B 2801 MSL1 ROHS+HF 3000 units/ Tape and Reel AW32805CSR -40°C～85°C WLCSP 1.34×1.78-12B 2805 MSL1 ROHS+HF 3000 units/ Tape and Reel AW32809CSR -40°C～85°C WLCSP 1.34×1.78-12B 2809 MSL1 ROHS+HF 3000 units/ Tape and Reel AW32812CSR -40°C～85°C WLCSP 1.34×1.78-12B 2812 MSL1 ti a l Part Number n ORDERING INFORMATION 3000 units/ Tape and Reel e ROHS+HF fi d AW328XX Shipping R: Tape & Reel a w in ic C o n Package Type CS: CSP www.awinic.com.cn 5 Copyright © 2014 SHANGHAI AWINIC TECHNOLOGY CO., LTD AW32801/AW32805/ AW32809/AW32812 June 2018 V1.2 PARAMETERS RANGE Supply Voltage Range VIN -0.3V to 29V -0.3V to 29V EN -0.3V to 6V Output Voltage Range ACOK -0.3V to 6V OUT See(NOTE 2) ti a OVLO Input Voltage Range Maximum Input Peak Pulse Voltage VIN_PUL (20μs pulse width, repeat 100 times) n 42V Maximum Continuous Current From IN to OUT ISW(NOTE 3) 4.5A Operating Free-air Temperature Range Maximum Junction Temperature TJMAX 1.5A 85°C/W -40°C to 85°C 165°C -65°C to 150°C n Storage Temperature TSTG fi d Junction-to-ambient Thermal Resistance θJA(NOTE 4) 8A e Peak Current From IN to OUT IPEAK (10ms) Maximum Continuous Forward Current Through the Switch Body Diode IDIODE 260°C Contact Discharge ±8kV Air Gap Discharge ±15kV Lead Temperature (Soldering 10 Seconds) l ABSOLUTE MAXIMUM RATINGS(NOTE1) C IEC61000-4-2 System ESD on IN (NOTE 5) o ESD ±4kV Charged Device Model (All pins, per JEDEC EIA/JESD22-C101F) ±1.5kV Machine Model (All pins, per JEDEC EIA/JESD22-A115) ±400V ic Human Body Model (All pins, per MIL-STD-883J Method 3015.9) (NOTE 6) Latch-Up in Test Condition: JEDEC STANDARD No.78C SEPTEMBER 2011 +IT：800mA -IT：-800mA w NOTE1: Conditions out of those ranges listed in "absolute maximum ratings" may cause permanent damages to the device.

ACOK will be driven low about 30ms after VIN valid, indicating the switch is on with a good ti a power input. If the input voltage exceeds the OVP trip level, the switch will be turned off in about 125ns. If EN is pulled high, or input voltage falls below UVLO threshold, or over-temperature happens, the switch will also be turned off. n Surge Protection fi d e The AW328XX integrates a clamp circuit to suppress input surge voltage. For surge voltages between VIN_OVLO and VIN_CLAMP, the switch will be turned off but the clamp circuit will not work. For surge voltages greater than VIN_CLAMP, the internal clamp circuit will detect surge voltage level and discharge the surge energy to ground. The device can suppress surge voltages up to 100V. Over-Voltage Protection n If the input voltage exceeds the OVP rising trip level, the switch will be turned off in about 125ns. The switch will remain off until VIN falls below the OVP falling trip level. OVP Threshold Adjustment o If OVLO pin is not grounded, and by connecting external resistor divider to OVLO pin as shown in the typical application circuit, between IN and GND, the OVP threshold can be adjusted as following: R1 +R2 VOVLO_TH R2 The adjustment range is 4V to 20V. When the OVLO pin voltage V OVLO exceeds VOVLO_SEL(0.42V typical), VOVLO is compared with the reference voltage VOVLO_TH (1.2V typical) to judge whether input supply is over-voltage. For example, if we select R1 = 51kΩ and R2 = 12.4kΩ, then the new OVP threshold calculated from the above formula is 6.14V. in ACOK Output ic C VIN_OVLO = The device features an open-drain output ACOK, it should be connected to the system I/O rail through a pull-up resistor. If the device is enabled and VIN_UVLO < VIN < VIN_OVLO, ACOK will be driven low indicating the w switch is on with a good power input. If OVP, UVLO, or OT occurs, or EN is pulled high, the switch will be turned off and ACOK will be pulled high. a USB On-The-Go (OTG) Operation If VIN = 0V and OUT is supplied by OTG voltage, the body diode of the load switch conducts current from OUT to IN and the voltage drop from OUT to IN is approximately 0.7V. When VIN > VIN_UVLO, internal charge pump begins to open the load switch after debounce time. After switch is fully on, current is supplied through switch channel and the voltage drop from OUT to IN is minimum. www.awinic.com.cn 12 Copyright © 2014 SHANGHAI AWINIC TECHNOLOGY CO., LTD AW32801/AW32805/ AW32809/AW32812 June 2018 V1.2 PCB LAYOUT CONSIDERATION To make full use of the performance of AW328XX, the guidelines below should be followed. l 1. All the peripherals should be placed as close to the device as possible. Place the input capacitor CIN on the top layer (same layer as the AW328XX) and close to IN pin, and place the output capacitor C OUT on the top layer (same layer as the AW328XX) and close to OUT pin. ti a 2. Red bold paths on figure 4 and 5 are power lines that will flow large current, please route them on PCB as straight, wide and short as possible. 3. If R1 and R2 are used, route OVLO line on PCB as short as possible to reduce parasitic capacitance. n 4. The power trace from USB connector to AW328XX may suffer from ESD event, keep other traces away from it to minimize possible EMI and ESD coupling. a w in ic C o n fi d e 5. Use rounded corners on the power trace from USB connector to AW328XX to decrease EMI coupling. www.awinic.com.cn 13 Copyright © 2014 SHANGHAI AWINIC TECHNOLOGY CO., LTD AW32801/AW32805/ AW32809/AW32812 June 2018 V1.2 TAPE AND REEL INFORMATION TAPE DIMENSIONS REEL DIMENSIONS P1 P2 P0 K0 l W ti a B0 D1 A0 Cavity e n A0：Dimension designed to accommodate the component width B0：Dimension designed to accommodate the component length K0：Dimension designed to accommodate the component thickness W：Overall width of the carrier tape P0：Pitch between successive cavity centers and sprocket hole P1：Pitch between successive cavity centers P2：Pitch between sprocket hole fi d D0 Q1 Q2 Q1 Q3 Q4 Q3 Q1 Q2 Q1 o Q2 n QUADRANT ASSIGNMENTS FOR PIN 1 ORIENTATION IN TAPE Q4 Q3 Q4 Q3 Sprocket Holes Q2 Q4 User Direction of Feed C Pocket Quadrants All Dimensions are normal Quantity Per D1：Reel Diameter Reel (mm) ic Package(mm) Pins AW328XXCSR WLCSP 1.34x1.78 12 3000 178.00 D0：Reel Width (mm) A0 (mm) B0 (mm) K0 (mm) P0 (mm) P1 (mm) P2 (mm) W (mm) Pin1 Quadrant 9.00 1.46 1.90 0.81 2.00 4.00 4.00 8.00 Q2 a w in Device www.awinic.com.cn 14 Copyright © 2014 SHANGHAI AWINIC TECHNOLOGY CO., LTD AW32801/AW32805/ AW32809/AW32812 June 2018 V1.2 PACKAGE DESCRIPTION BOTTOM VIEW e2 E Ball A1 e4 ti a e3 A l TOP VIEW B e1 D 12X Ø0.268±0.020 C Symbol A A1 A2 NOM 0.575 0.195 fi d n 2 n 1 A3 D E e1 0.340 0.040 1.340 1.780 0.400 e2 e3 e4 0.200 0.400 0.400 Tolerance ±0.055 ±0.020 ±0.025 ±0.010 ±0.025 ±0.025 NA NA NA NA Unit: mm a w in ic C o A1 A2 A3 A SIDE VIEW 3 e 4 www.awinic.com.cn 15 Copyright © 2014 SHANGHAI AWINIC TECHNOLOGY CO., LTD AW32801/AW32805/ AW32809/AW32812 June 2018 V1.2 LAND PATTERN DATA 1.200 0.200 0.400 n 0.800 ti a l 0.400 Ø0.240 Copper Pad Diameter fi d e Ø0.340 Solder Mask Opening a w in ic C o n NSMD Pad Type Unit: mm www.awinic.com.cn 16 Copyright © 2014 SHANGHAI AWINIC TECHNOLOGY CO., LTD AW32801/AW32805/ AW32809/AW32812 June 2018 V1.2 n Reflow Note Package Reflow Standard Profile o Figure 19 fi d e n ti a l REFLOW C Average ramp-up rate (217°C to peak) Spec Max. 3°C /sec 60-120sec Time to be maintained above 217°C 60-150sec Peak Temperature 250-260°C ic Time of Preheat temp.
