Description:
DIP-IPMs are intelligent power
modules that integrate power
devices, drivers, and protection
circuitry in an ultra compact
dual-in-line transfer-mold package
for use in driving small three
phase motors. Use of 5th generation CSTBT Chip Technology,
DIP packaging, and application
specific HVICs allow the designer
to reduce inverter size and overall
design time.
Features:
£ Compact Packages
£ Single Power Supply
£ Integrated HVICs
£ Direct Connection to CPU
Applications:
£ Washing Machines
£ Refrigerators
£ Air Conditioners
£ Small Servo Motors
£ Small Motor Control
Ordering Information:
PS21267-P (short pin) /
PS21267-AP (long pin) are 600V,
30 Ampere DIP Intelligent Power
Modules.

*The maximum junction temperature rating of the power chips integrated within the DIP-IPM is 150°C (@TC ≤ 100°C). However, to ensure safe operation of the DIP-IPM,
the average junction temperature should be limited to Tj(avg) ≤ 125°C (@TC ≤ 100°C).

* Short-Circuit protection is functioning only at the lower arms. Please select the value of the external shunt resistor such that the SC trip level is less than 30A.
**Fault signal is asserted when the lower arm short circuit or control supply under-voltage protective functions operate. The fault output pulse-width tFO depends on the capacitance value
of CFO according to the following approximate equation: CFO = (12.2 x 10-6) x tFO {F} .

* The allowable rms current value depends on the actual application conditions.
**If input signal ON pulse is less than PWIN(on), the device may not respond.
***The IPM may fail to respond to an ON pulse if the preceeding OFF pulse is less than PWIN(off).

Notes:
1) To prevent input signal oscillations minimize wiring length to controller (~2cm). Additional RC filtering (C5 etc.) may be
required. If filtering is added be careful to maintain proper dead time. See application notes for details.
2) Internal HVIC provides high voltage level shifting allowing direct connection of all six driving signals to the controller.
3) FO output is an open collector type. Pull up resistor (R3) should be adjusted to current sink capability of the module.
4) C4 sets the fault output duration and lock-out time. C4 12.2E-6 x tFO, 22nF gives ~1.8ms
5) Boot strap supply component values must be adjusted depending on the PWM frequency and technique.
6) Wiring length associated with RSHUNT, RSF, CSF must be minimized to avoid improper operation of the SC function.
7) RSF, CSF set short-circuit protection trip time. Recommend time constant is 1.5us-2.0us. See application notes.
8) Local decoupling/high frequency filter capacitors must be connected as close as possible to the modules pins.
9) The length of the DC link wiring between C6, C7, the DIP’s P terminal and the shunt must be minimized to prevent
excessive transient voltages. In particular C7 should be mounted as close to the DIP as possible.
10) Use high quality, tight tolorance current sensing resistor. Connect resistor as close as possible to the DIP’s
N terminal. Be careful to check for proper power rating. See application notes for calculation of resistance value.
