Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

General Description
FSBB20CH60CT is an advanced Motion SPM® 3 mod-
ule providing a fully-featured, high-performance inverter
output stage for AC Induction, BLDC, and PMSM
motors. These modules integrate optimized gate drive of
the built-in IGBTs to minimize EMI and losses, while also
providing multiple on-module protection features includ-
ing under-voltage lockouts, over-current shutdown, and
fault reporting. The built-in, high-speed HVIC requires
only a single supp ly voltage and translates the incoming
logic-level gate inputs to the high-voltage, high-current
drive signals required to properly drive the module's
internal IGBTs. Separate negative IGBT terminals are
available for each phase to support the widest variety of
control algorithms.

Figure 13. Typical Application Circuit
4th Notes:
1. To avoid malfunction, the wiring of each input should be as short as possible (less than 2 - 3cm).
2. By virtue of integrating an application-specific type of HVIC inside the Moti on SPM® 3 product, direct coupling to MCU terminals without any optocoupler or transformer isola-
tion is possible.
3. VFO output is open-collector type. This signal line should be pulled up to the positive side of the 5 V power supply with approximately 4.7 k resistance (please refer to
Figure11).
4. CSP15 of around seven times larger than bootstrap capacitor CBS is recommended.
5. VFO output pulse width sh ou ld be d ete rm ine d b y con ne cting an external capacitor (CFOD) between CFOD (pin 7) and COM (pin 2). (Example: if CFOD = 33 nF, then tFO = 1.8 ms
(typ.)) Please refer to the 2nd note 5 for calculation method.
6. Input signal is active-HIGH type. There is a 5 k resistor insi de t he I C to pull down each inp ut si gnal lin e to GND. RC coupl ing circu it s shou ld be us ed t o prev ent i npu t sig nal
oscillation. RSCPS time constant should be selected in the range 50 ~ 150 ns. CPS should not be less than 1 nF (recommended RS = 100 Ω, CPS = 1 nF).
7. To prevent errors of the protection function, the wiring around RF and CSC should be as short as possible.
8. In the short-circuit protection circuit, please select the RFCSC time constant in the range 1.5 ~ 2.0 s.
9. Each capacitor should be mounted as close to the pins of the Motion SPM 3 product as possible.
10. To prevent surge destr uction, the wiring between the smoothing capacitor and the P & GND pins should be as short as possible. The use of a high-frequency non-inductive
capacitor of around 0.1 ~ 0.22 F between the P & GND pins is recommended.
11. Relays are used in almost every systems of electrical equipment in home appliances. In these cases, th ere should be sufficient distance between the MCU and the relays.
12. CSPC15 should be over 1 F and mounted as c lose to the pi ns of the Motion SPM 3 product as possible.
