TMP816PWR

Texas Instruments · Brushed DC Motor Drivers · TSSOP-20

TMP816PWR 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 H-bridge stage
2 OUT2N output Lower-side driver output for the second H-bridge stage
3 VCC power_in Power supply input; connect 0.1 μF to 1 μF decoupling capacitor with thick pattern and shortest route
4 VLIM input Current limiter threshold input; activates current limiter when SENSE voltage exceeds VLIM
5 SENSE input Current sense input from series resistor in motor circuit; connect to GND when not used
6 RMI input Minimum speed setting input; connect to 6VREG when not used
7 VTH input Speed control voltage input filtered from PWM signal; supports 20 kHz to 100 kHz PWM input frequency
8 CPWM output PWM frequency setting output; connect external capacitor (100 pF for 25 kHz oscillation frequency)
9 FG tri_state Open collector motor speed feedback output; detects rotation speed via phase shift
10 RD tri_state Open collector lock detection output; outputs low during rotation and high at motor stop
11 IN- input Hall sensor negative input terminal
12 HB output Hall sensor bias output; provides 1.5-V constant-voltage supply for Hall elements
13 IN+ input Hall sensor positive input; keep traces short to minimize noise; ensure signal amplitude exceeds 60 mVp-p
14 CT output Lock detection capacitor connection; external capacitor determines lock detection timeout period
15 ROFF input Reactive current cut-off time setting input; sets soft-switching time to cut reactive current before phase change
16 6VREG power_out 6-V regulated output for Hall sensor and circuit pull-up supplies; provides 5.8 V to 6.15 V at 5 mA load
17 SGND power_in Ground connection for control circuit power supply system
18 SS output Soft-start capacitor connection; external capacitor between 6VREG and SS sets soft-start time
19 OUT1N output Lower-side driver output for the first H-bridge stage
20 OUT1P output Upper-side driver output for the first H-bridge stage
