TMP814PWR

Texas Instruments · Brushless DC (BLDC) Motor Driver · TSSOP-20

TMP814PWR from Texas Instruments, in a TSSOP-20. 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 OUT2P output Upper-side driver output for the second coil leg, intended to drive the P-channel top-side switch of the H-bridge.
2 OUT2N output Lower-side driver output for the second coil leg, intended to drive the N-channel bottom-side switch of the H-bridge.
3 VCC power_in Supply input for the device; a 0.1 µF to 1 µF capacitor (CM) is connected between VCC and GND close to the pin, and a zener diode should be used if kickback causes excessive supply rise, with recommended supply of 6 V to 16 V and an 18 V absolute maximum.
4 VLIM input Current-limit threshold input that activates the current limiter when the SENSE voltage exceeds the VLIM voltage, and must be connected to 6VREG when not used.
5 SENSE input Current sense input for the current limiter in the H-bridge return path, and must be connected to GND when not used.
6 RMI input Minimum speed setting input set by an external resistor; connect to 6VREG when not used, and insert a current-limiting resistor if device power may be removed before power is removed from RMI to prevent large inflow current.
7 VTH input Speed control input that accepts a DC voltage (0 V to 7 V in full-speed mode) or a pulsed PWM signal, and must be connected to GND for full speed when speed control is not used.
8 CPWM output PWM oscillator timing pin where a capacitor sets the PWM oscillation frequency (CP = 100 pF gives 25 kHz), and the capacitor must be fitted even when speed control is not used.
9 FG output Open-collector rotation speed output derived from the phase shift of the drive, which requires an external pull-up and should be left open when not used.
10 RD output Open-collector lock detection output that is low during rotation and high at stop, and should be left open when not used.
11 IN- input Negative Hall sensor input to the internal comparator, with traces kept short and an optional capacitor between IN+ and IN- to limit noise.
12 HB output Hall element bias output providing a 1.5 V constant-voltage output for the Hall sensor.
13 IN+ input Positive Hall sensor input to a comparator with 20 mV hysteresis, where the Hall input level should be at least three times the hysteresis (60 mVp-p).
14 CT output Lock detection timing pin to which the lock detection capacitor is connected; the lock detection feature is disabled if this pin is tied to ground.
15 ROFF input Soft-switching time setting input that sets the soft switching time to cut reactive current before phase change, and must be connected to 6VREG when not used.
16 6VREG output 6 V regulator output that supplies Hall bias, pull-ups and the pin-setting connections, specified at 5.8 V to 6.15 V at 5 mA load.
17 SGND power_in Signal ground connected to the control circuit power supply system.
18 VOVER output Constant-voltage bias output used for 24 V and 48 V operation to limit VCC to permissible values, which requires a current-limiting resistor and should be left open when not used.
19 OUT1N output Lower-side driver output for the first coil leg, intended to drive the N-channel bottom-side switch of the H-bridge.
20 OUT1P output Upper-side driver output for the first coil leg, intended to drive the P-channel top-side switch of the H-bridge.
