Texas Instruments · Gate Drivers · SSOP-24-208mil

TPIC44L01DBR from Texas Instruments, in a SSOP-24-208mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 FLT output Open-drain logic-level real-time fault flag for shorted-load, open-load, over-battery and under-battery faults, which requires an external pullup resistor.
2 VCOMPEN input Fault reference select: connecting it to GND selects the internal fault reference and connecting it to VCC selects the external VCOMP reference.
3 VCOMP input External fault reference voltage input for shorted-load and open-load detection, used only when VCOMPEN is connected to VCC.
4 IN0 input Parallel gate control input for channel 0 with CMOS-compatible hysteresis, where a 1 turns GATE0 on and a 0 turns it off.
5 IN1 input Parallel gate control input for channel 1 with CMOS-compatible hysteresis, where a 1 turns GATE1 on and a 0 turns it off.
6 IN2 input Parallel gate control input for channel 2 with CMOS-compatible hysteresis, where a 1 turns GATE2 on and a 0 turns it off.
7 IN3 input Parallel gate control input for channel 3 with CMOS-compatible hysteresis, where a 1 turns GATE3 on and a 0 turns it off.
8 CS input Chip select: a high-to-low transition enables SDO, latches fault data and refreshes FLT, and a low-to-high transition latches serial data into the output control register; it has a pullup resistor.
9 SDO tri_state Serial data output, a 3-state output that transfers fault data and passes serial input data to the next stage, and is high-impedance while CS is high.
10 SDI input Serial data input clocked into the serial register on SCLK, where a 1 commands the gate output on and a 0 turns it off.
11 SCLK input Serial clock that shifts data into SDI and clocks serial fault data out of SDO on the falling edge.
12 VCC power_in Logic supply voltage, recommended 4.5 V to 5.5 V with 5 V nominal.
13 GND power_in Ground and substrate reference for all voltages on the device.
14 DRAIN3 input FET drain input for channel 3 used for open-load and shorted-load fault detection and inductive transient protection.
15 GATE3 output Gate drive output for the channel 3 external FET, derived from VBAT and clamped to protect the FET VGS rating.
16 DRAIN2 input FET drain input for channel 2 used for open-load and shorted-load fault detection and inductive transient protection.
17 GATE2 output Gate drive output for the channel 2 external FET, derived from VBAT and clamped to protect the FET VGS rating.
18 GATE1 output Gate drive output for the channel 1 external FET, derived from VBAT and clamped to protect the FET VGS rating.
19 DRAIN1 input FET drain input for channel 1 used for open-load and shorted-load fault detection and inductive transient protection.
20 GATE0 output Gate drive output for the channel 0 external FET, derived from VBAT and clamped to protect the FET VGS rating.
21 DRAIN0 input FET drain input for channel 0 used for open-load and shorted-load fault detection and inductive transient protection.
22 RESET input Active-low reset: a high-to-low transition clears all registers and flags, turns the gate outputs off and clears FLT, and it has a pullup resistor.
23 N/C unconnected Not connected; the pin is shown as N/C in the pin diagram and has no function listed.
24 VBAT power_in Battery supply voltage, recommended 8 V to 24 V, with an absolute maximum of 60 V.
