NCS5652, NCV5652 Dual Power Operational Amplifier Description The NCx5652 is a dual power operational amplifier with a versatile output stage configuration that allows conventional opamp biasing or www.onsemi.com user tuning of efficiency, isolation, or current monitoring. Integrated flyback diodes protect the amplifiers during inductive load transients. Operating at supply voltages as low as 3.3 V, the NCx5652 is capable of delivering 500 mA of current while maintaining an excellent output swing. The integrated thermal shutdown circuit protects the NCx5652 1 from excessive power dissipation. A thermal warning flag is provided UDFN12 for external monitoring of the device, providing a flexible interface to MU SUFFIX a systems microcontroller. This opencollector thermal flag output CASE 517AM doubles as a DISABLE input that can be used to tristate both amplifier outputs under user control. The 12pin UDFN 3x3 mm package provides thermal robustness while achieving space savings MARKING DIAGRAM on high density PCBs.

PIN DESCRIPTION Pin Name Type Description 1 IN1 Input Negative input of amplifier 1. 2 IN1+ Input Positive input of amplifier 1. 3 DISABLE/Tflag Input/Output Dual use pin Thermal flag an open collector output requiring an external pullup resistor. The output is pulled low when the thermal limit is reached. It is highimpedance in normal operation. Disable Must use an open collector/drain for input with pullup resistor to Vcc. Pulling pin low disables the amplifiers. If pin is not used, a pullup resis- tor to Vcc is still required (10 K recommended) 4 IN2+ Input Positive input of amplifier 2. 5 IN2 Input Negative input of amplifier 2. 6 GND Power Power ground. 7 OUT2 Output Output of amplifier 2. 8 VC2 Power Positive supply of output stage 2. 9 VCC Power Positive supply of core circuitry. 10 VC1 Power Positive supply of output stage 1. 11 OUT1 Output Output of amplifier 1. 12 GND Power Power ground. 13 EXPOSED PAD Power The Exposed Pad must be attached to a heatsinking conduit and connected to GND. www.onsemi.com 2
