MCP6C02 Zero-Drift, 65V High-Side Current Sense Amplifier Features General Description Single Amplifier: MCP6C02 The Microchip Technology Inc. MCP6C02 high-side current sense amplifier is offered with preset gains of Bidirectional or Unidirectional 20, 50 and 100 V/V. The Common-mode input range Input (Common-mode) Voltages: (V ) is +3V to +65V. The differential-mode input range IP - +3.0V to +65V, specified (V =V V ) supports unidirectional and DM IP IM - +2.8V to +68V, operating bidirectional applications. - -0.3V to +70V, survival The power supply can be set between 2.0V and 5.5V. Power Supply: This device is specified from -40C to +125C (E-Temp) - 2.0V to 5.5V and is provided in the SOT-23 package. - Single or Dual (Split) Supplies The Zero-Drift architecture supports very low input High DC Precision errors, which allow a design to use shunt resistors of lower value (and lower power dissipation). -V : 1.65 V (typical) OS - CMRR: 154 dB (typical) Package Types - PSRR: 138 dB (typical) - Gain Error: 0.1% (typical) MCP6C02 Preset Gains: 20, 50 and 100 V/V 6-Lead SOT-23 POR Protection - HV POR for V V IP SS V V OUT 1 6 DD - LV POR for V V DD SS Bandwidth: 500 kHz (typical) V V SS 2 5 REF Supply Current: 490 A (typical) V V Enhanced EMI Protection: IP 3 4 IM - EMIRR: 118 dB at 2.4 GHz (typical) Extended Temperature Range (E-Temp): - -40C to +125C Typical Application Circuit Typical Applications +5V Motor Control 2.2 F Analog Level Shifter 10 nF U (DUT) Industrial Computing 1 100 nF Battery Monitor/Tester MCP6C02-100 V BAT R SH V OUT +36V 2.2 m 20 k I <20A L V L 2018 Microchip Technology Inc.
