## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RUN | input | Run control input: above 1.21V enables normal operation, while forcing it below 0.7V shuts down the LTC7003 with quiescent current reduced to about 1µA; an optional resistive divider from the input supply sets the undervoltage lockout. |
| 2 | VIN | power_in | Main supply pin with an operating range of 3.5V to 60V (absolute maximum -0.3V to 65V), requiring a bypass capacitor of at least 0.1µF to GND. |
| 3 | VCC | power_out | Output of the internal LDO that powers the gate drivers and internal circuitry, to be decoupled to GND with at least 1.0µF low-ESR ceramic; it may be overdriven externally but must never be driven above VIN. |
| 4 | VCCUV | input | VCC undervoltage lockout reference: a voltage of 0.4V to 1.5V on this pin is multiplied by 7 to set the gate drive UVLO, which is 3.5V when shorted to GND and 7.0V when left open. |
| 5 | FAULT | output | Open-drain fault output that pulls low when the TIMER pin reaches the 1.3V fault threshold to warn of an impending overcurrent turn-off, with a typical pull-down impedance of 200Ω and release only after the overcurrent condition and cooldown period expire. |
| 6 | TIMER | passive | Fault timer input where a capacitor CT to GND sets the fault warning, fault turn-off and retry periods; pulling it above 3.5V disables the timer, and connecting it to VCC selects fast turn-off mode. |
| 7 | INP | input | CMOS-compatible input referenced to GND that sets the state of the TGDN and TGUP outputs, with an internal 1MΩ pull-down to GND that holds TGDN at TS during startup transients. |
| 8 | OVLO | input | Overvoltage lockout input where a voltage above 1.21V pulls TGDN to TS and causes a fault, with normal operation resuming below 1.11V; it should be tied to GND when not used. |
| 9 | ISET | passive | Current trip threshold setting where a resistor to GND sets the comparator threshold ΔVTH to V(ISET)/20 with the pin clamped between 0.4V and 1.5V, giving 20mV when shorted to GND and 30mV when open or above 2.0V. |
| 10 | IMON | output | Current monitor output equal to 20 times the sense resistor voltage, with a range of 0V to 1.5V and an output impedance of 100kΩ. |
| 11 | TGDN | output | High current gate driver pull-down that pulls the external MOSFET gate to TS; it should be tied directly to the MOSFET gate for the fastest turn-off. |
| 12 | TGUP | output | High current gate driver pull-up to BST; it should be tied to TGDN for maximum transition speed, and a resistor may be added between this pin and the MOSFET gate to limit turn-on inrush current. |
| 13 | TS | power_in | Top (high side) source connection of the external MOSFET, or GND in ground-referenced applications, with a specified operating voltage range of 0V to 60V. |
| 14 | BST | power_out | High side bootstrapped supply, requiring a minimum 0.1µF capacitor to TS, with a voltage swing from 12V to (VIN + 12V) and an absolute maximum of 80V. |
| 15 | SNS- | input | Current sense comparator input connected to the sense resistor through a minimum 100Ω resistor, with an input voltage range of 3.5V to 60V independent of VIN. |
| 16 | SNS+ | input | Current sense comparator input that should use a Kelvin connection to the sense resistor, with an input voltage range of 3.5V to 60V independent of VIN. |
| 17 | GND | power_in | Exposed pad ground that must be soldered to the PCB for rated electrical and thermal performance. |
