Texas Instruments · Gate Drivers · SSOP-28-208mil

TPIC46L01DBR from Texas Instruments, in a SSOP-28-208mil. 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 tri_state Open-drain output providing real-time fault flag for shorted-load, open-load, over-battery voltage, and under-battery voltage faults; requires external pullup resistor.
2 VCOMPEN input Fault reference voltage select; connect to GND for internally generated fault reference or to VCC for external VCOMP fault reference.
3 VCOMP input Fault reference voltage input providing external fault reference for shorted- and open-load fault detection circuitry.
4 IN0 input Real-time parallel control input for gate predrive circuitry; CMOS compatible with hysteresis.
5 IN1 input Real-time parallel control input for gate predrive circuitry; CMOS compatible with hysteresis.
6 IN2 input Real-time parallel control input for gate predrive circuitry; CMOS compatible with hysteresis.
7 IN3 input Real-time parallel control input for gate predrive circuitry; CMOS compatible with hysteresis.
8 IN4 input Real-time parallel control input for gate predrive circuitry; CMOS compatible with hysteresis.
9 IN5 input Real-time parallel control input for gate predrive circuitry; CMOS compatible with hysteresis.
10 CS input Chip select input; high-to-low transition enables SDO, latches fault data into serial interface, and refreshes fault flag.
11 SDO tri_state 3-state serial data output transferring fault data and cascaded serial input data; high-impedance state when CS is high.
12 SDI input Serial data input for output control data clocked into serial register; 1 commands gate output on, 0 turns it off.
13 SCLK input Serial clock input clocking shift register; serial data clocked into SDI and fault data clocked out of SDO on falling edge.
14 VCC power_in Logic supply voltage, 4.5V minimum to 5.5V maximum.
15 GND power_in Ground and substrate.
16 GATE5 output Gate drive output for external FET derived from VBAT supply; internal clamps prevent voltages from exceeding FET VGS rating.
17 DRAIN5 input Drain input for external FET used for open-load and short-circuit fault detection and inductive transient protection.
18 GATE4 output Gate drive output for external FET derived from VBAT supply; internal clamps prevent voltages from exceeding FET VGS rating.
19 DRAIN4 input Drain input for external FET used for open-load and short-circuit fault detection and inductive transient protection.
20 DRAIN3 input Drain input for external FET used for open-load and short-circuit fault detection and inductive transient protection.
21 GATE3 output Gate drive output for external FET derived from VBAT supply; internal clamps prevent voltages from exceeding FET VGS rating.
22 GATE2 output Gate drive output for external FET derived from VBAT supply; internal clamps prevent voltages from exceeding FET VGS rating.
23 DRAIN2 input Drain input for external FET used for open-load and short-circuit fault detection and inductive transient protection.
24 DRAIN1 input Drain input for external FET used for open-load and short-circuit fault detection and inductive transient protection.
25 GATE1 output Gate drive output for external FET derived from VBAT supply; internal clamps prevent voltages from exceeding FET VGS rating.
26 DRAIN0 input Drain input for external FET used for open-load and short-circuit fault detection and inductive transient protection.
27 GATE0 output Gate drive output for external FET derived from VBAT supply; internal clamps prevent voltages from exceeding FET VGS rating.
28 VBAT power_in Battery supply voltage input, 8V minimum to 24V maximum.
