ROHM Semicon · Motor Driver ICs · VQFN-24-EP(4x4)

BD61250MUV-E2 from ROHM Semicon, in a VQFN-24-EP(4x4). 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 GND power_in Ground.
2 FSEL input Drive PWM frequency select: open gives 50kHz, shorted to GND gives 25kHz (low level -0.3 to 0.8V).
3 SSEL input FG/AL signal select for SIG: open gives FG, shorted to GND gives AL (low level -0.3 to 0.8V).
4 STBEN input Standby mode enable select: open enables the standby function, GND disables it (low level -0.3 to 0.8V).
5 CS input Current sensing input for the current limit (current limit voltage 160mV typ); absolute maximum input 5.3V.
6 N.C. unconnected No internal connection.
7 N.C. unconnected No internal connection.
8 A2L output Low side output 2 driving the external MOSFET gate (0 to 7V, max 10mA).
9 A2H output High side output 2 driving the external MOSFET gate (VCC-7V to VCC, max 10mA).
10 A1L output Low side output 1 driving the external MOSFET gate (0 to 7V, max 10mA).
11 A1H output High side output 1 driving the external MOSFET gate (VCC-7V to VCC, max 10mA).
12 VCC power_in Power supply, 4.5 to 36V recommended operating, 40V absolute maximum.
13 SIG output Open-drain FG/AL signal output, 40V and 10mA absolute maximum.
14 PWMIN input PWM signal input, high level 2 to 5.3V, low level -0.3 to 0.8V, input frequency 1 to 100kHz.
15 REF power_out Reference voltage output, 3.0V typ at IREF=-1mA, 10mA absolute maximum output current.
16 HP input Hall signal input +, 0 to 2V recommended, 3.3V absolute maximum.
17 HM input Hall signal input -, 0 to 2V recommended, 3.3V absolute maximum.
18 ADJ input Output duty correction pin (ADC input terminal, 3.3V absolute maximum).
19 LA input Lead angle setting pin (ADC input terminal, 3.3V absolute maximum).
20 LZ input Re-circulate angle setting pin (ADC input terminal, 3.3V absolute maximum).
21 MIN input Minimum output duty setting pin (ADC input terminal, 3.3V absolute maximum).
22 SLP input Input-output duty slope setting pin (ADC input terminal, 3.3V absolute maximum).
23 SST input Soft start time setting pin (ADC input terminal, 3.3V absolute maximum).
24 SSW input Soft switching angle setting pin (ADC input terminal, 3.3V absolute maximum).
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
