TC46271.5 A MOSFET Gate Driver with Voltage Tripler | Power Management (PMIC) | 6 | Active | The TC4626/4627 are single CMOS high speed gate drivers with an on-board voltage boost circuit. These parts work with an input supply voltage from 4 to 6 V. The internal voltage booster will produce a VBOOST potential up to 12 V above VIN. This VBOOST is not regulated, so its voltage is dependent on the input VDD voltage and output drive loading requirements. An internal under voltage lockout (UVLO) circuit keeps the output in a low state when VBOOST drops below 7.8 V. Output is enabled when VBOOST is above 11.3 V. |

| Integrated Circuits (ICs) | 5 | Active | The TC500A is a precision analog front end dual slope A/D converter having a maximum resolution of 17 bits plus sign. The device contains the integrator, zero crossing comparator and processor interface logic. The TC500A is identical to the TC500, except it has improved linearity allowing it to operate to a maximum resolution of 17 bits. The TC500A offers superior 50Hz/60Hz noise rejection, low power operation, minimum I/O connections, and low input bias currents. |

TC51N1uA Voltage detector with Output Delay | Integrated Circuits (ICs) | 1 | Active | The TC51 is a very low power, open drain output, CMOS voltage detector with built-in delay. It is particularly well-suited for battery powered applications because of its extremely low 1µA operating current and small surface-mount packaging. Each part is laser-trimmed to the desired threshold voltage, which can be specified from 1.6V to 6.0V. The standard built-in output delay is 50msec-200msec. The device includes a comparator, low-current highprecision reference, laser-programmed voltage divider, hysteresis circuit and output driver with digital delay timer. In operation, the TC51’s output (VOUT) remains in the logic HIGH state as long as VIN is greater than the specified threshold voltage (VDET -). When VIN falls below VDET -, the output is immediately driven to a logic LOW. VOUT remains LOW until VIN rises above VDET - by an amount VHYST, whereupon it returns to a logic HIGH after expiration of the built-in delay time. |
TC520ASerial Interface Adapter for TC5x0 ADC | Interface | 1 | Active | The TC520A Serial Interface Adapter provides logic control for Microchip's TC500/500A/510/514 family of dual slope,integratingA/Dconverters. ItdirectlymanagesTC500 converter phase control signals A, B, and CMPTR thereby reducing host processor task loading and software complexity. Communication with the TC520A is accomplished over a 3wire serial port. Key converter operating parameters are programmable for complete user flexibility. Data conversion initiated when the CE input is brought low. The converted data (plus overrange and polarity bits) are held in an 18 bit shift register until read by the processor, or until the next conversion is completed. Data may be clocked out of the TC520A at any time, and at any rate the user prefers. A Data Valid (DV) output is driven active at the start of each conversion cycle indicating the 18 bit shift register update has just been completed. This signal may be polled by the processor, or can be used as data ready interrupt. The TC520A timebase can be derived from an external frequency source of up to 6MHz; or can operate from its own external crystal. It requires a single 5V logic supply and dissipates less than 7.5mW. |
