LTM4653
PIN FUNCTIONS IMONb (C1):
Power Inductor Analog Indicator Current De-
TEMP– (J2, J7):
Temperature Sensor, Negative Input. fault Termination R-C Network. A 10kΩ resistor in parallel Collector and base of a 2N3906-genre PNP bipolar junc- with a 10nF capacitor and terminating to SGND connect tion transistor (BJT). Optionally interface to temperature to this pin. Connect IMONb to IMONa to achieve default monitoring circuitry such as LTC2997, LTC2990, LTC2974 power inductor analog indicator current characteristics: or LTC2975. Otherwise leave electrically open. Pins J2 1V at full scale (4A) load current. (See IMONa.) and J7 are electrically connected together internal to the
TEMP+ (J1, J6):
Temperature Sensor, Positive Input. LTM4653, and thus it is only necessary to connect one Emitter of a 2N3906-genre PNP bipolar junction transis- TEMP– pin to monitoring circuitry. The remaining TEMP– tor (BJT). Optionally interface to temperature monitor- pin can be used for redundant connectivity or routed to an ing circuitry such as LTC®2997, LTC2990, LTC2974 or ICT test point for design-for-test considerations, as desired. LTC2975. Otherwise leave electrical y open. Pins J1 and J6
SW (H4):
Switching Node of Switching Converter Stage. are electrically connected together internal to the LTM4653, Used for test purposes. May be routed a short distance and thus it is only necessary to connect one TEMP+ pin with a thin trace to a local test point to monitor switching to monitoring circuitry. The remaining TEMP+ pin can be action of the converter, if desired, but do not route near any used for redundant connectivity or routed to an ICT test sensitive signals; otherwise, leave electrically open circuit. point for design-for-test considerations, as desired.
NC (A6-7, B2, B6-7, C6-7, D6-7, E6-7, F6-7, G6-7, H6-7, K6-7, L6-7):
No connect pins, i.e., pins with no internal connection. The NC pins predominantly serve to provide improved mounting of the module to the board. In one’s layout, NC pins are permitted to remain electrically uncon- nected or can be connected as desired, e.g., connected to a GND plane for heat-spreading purposes and/or to facilitate routing.
