UC3770BN

Texas Instruments · Gate Drive ICs · PDIP-16

UC3770BN from Texas Instruments, in a PDIP-16. 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 BOUT output Bridge output B of the H-bridge; output current is rated up to ±2A.
2 Timing passive Monostable timing pin where the RT/CT network sets the off time, tOFF = 0.69RTCT.
3 VM power_in Motor supply voltage input, 10V to 45V operating range (50V absolute maximum).
4 Gnd power_in Ground; the reference for all voltages, and internally connected with pins 5, 12 and 13.
5 Gnd power_in Ground; the reference for all voltages, and internally connected with pins 4, 12 and 13.
6 VCC power_in Logic supply voltage, 4.75V to 5.3V (7V absolute maximum).
7 I1 input LS-TTL compatible logic input that selects the current level, with threshold 0.8V to 2.0V and 6V absolute maximum.
8 Phase input LS-TTL compatible logic input that sets the direction of the bridge output current, with threshold 0.8V to 2.0V and 6V absolute maximum.
9 I0 input LS-TTL compatible logic input that selects the current level, with threshold 0.8V to 2.0V and 6V absolute maximum.
10 Current input Current-sense comparator input, which is limited to VCC maximum and has an input current of ±20µA maximum.
11 VR input Reference input voltage for the current-sense thresholds, 15V absolute maximum.
12 Gnd power_in Ground; the reference for all voltages, and internally connected with pins 4, 5 and 13.
13 Gnd power_in Ground; the reference for all voltages, and internally connected with pins 4, 5 and 12.
14 VM power_in Motor supply voltage input, 10V to 45V operating range (50V absolute maximum).
15 AOUT output Bridge output A of the H-bridge; output current is rated up to ±2A.
16 Emitters passive Common emitter connection of the low-side drivers, where the external current-sense resistor is connected.
