When using it usually through a switching regulator It is as a 2/15- page block diagram between Vout and FB terminal. Please connect a coil capacitor diode . 2. When S/W- REG is not used but voltage is given to a direct FB terminal from the exterior A coil capacitor diode is unnecessary. Protection function When voltage is given to a direct FB terminal from the exterior, Current can decrease by about 1mA at the time of Vp standby. Vout terminal 1. 2. FB terminal 1. 2. It has the Gnd short protection function at the time of starting.l It does not have the Gnd short protection function under operation. The Gnd short protection function at the time of starting serves as only a current limit. During operation, it has the function to make Vout turn off by combined use of current limit detection and a Low Voltage detection machine. Sequence of operation at the time of starting. Usually, a state: Power supply injection → With no GND short → Vout-FB and charge pump operation GND short state: Power supply injection → GND short → Vout-FB un-operating Charge pump operation Sequence during operation. Vout GND short: Vout operation → GND short judging → Vout-FB and charge pump operation FB GND short: FB operation → Current limit operation → GND short judging → Vout-FB OFF. Charge pump operation When FB voltage becomes less than [more than 1us4.2V] by current limit detection It becomes a GND short judging and Vout ismade to turn off. *1 GND short detection function: GND short detection performs GND short detection at the time of starting, It does not have the GND short detection function under operation.

FET is set to all OFF when current flows in the right direction. 2, RESET terminal Low: All data reset(All FET OFF)High :Data setup Standby state When a RESET terminal is set to “L” and a Motor drive is performed, A REST terminal is set to “H” and serial data is re inputted. Internal logic reset is Logic composition of a RESET terminal and a Low Voltage detection machine is performed. When rapid high load is in FB, a Low Voltage detection machine outputs “L”, Internal logic is reset when an output does not return to less than 1 µs at “H.” RESET terminal “L” ⋅Internal logic will be in an initial state.(All FET serves as all OFF ) ⋅A S/W- REG part continues operation. 3, EN terminal Low: External PWM Mode Slow Decay or Fast Decay Off Time ⋅Fast Decay Time: Sleep A current detection condition setup at the time of Decay is performed by Sync.Rect.Control Active or Passive. However, current detection is effective only at the time of Fast Decay.(Slow is invalid.) High :Internal PWM Mode Motor drive state FET ON- >OFF - >ON 4, Motor drive Motor drive :RESET terminal “H” EN terminal “H” It drives after a Mode Data setup. Motor STOP :RESET terminal “L” is STOP. RESET terminal “H” EN terminal “L”: It is set to Decay by External PWM Mode. All FETOFF comes after setting current detection. EN is not related to “L or H” in early stages. It FET all turns off till control logic initial setting and the completion of a Mode setting. EN is always after control logic initial setting and the completion of a Mode setting at “L.”, If it is External PWM Slow Decay Mode, it is Start about Slow Decay. (It FET all turns off at the time of Fast Decay Mode.) After control logic initial setting and the completion of a Mode setting, FET is set to being turned on by EN “H” and it is compulsorily set to Decay Mode by EN “L.” However, even if a setup of External PWM Slow Decay Mode is EN “L”, it is reflected. 5, Current detection by Decay The conditions which perform current detection by Decay Internal PWM: Sync.Rect.EnableControl1 “H”, Inside of Fast Decay in Mixed Decay Mode External PWM: Sync.Rect.EnableControl1 “H”, Fast Decay Mode In addition, Decay current detection is not performed on conditions. Internal PWM: It changes to Decay from FET ON by the current detection COM., Fast Decay Time-OffTime starts in this stage. It is Start about the current detection in Decay, Fast Decay Time as a trigger. Detection is stopped after Fast Decay Time completion. When setting Decay current is detected during Fast Decay time, FET is all turned off only within Fast Decay time. It is referred to as Slow Decay till OFF Time completion after Fast Decay completion. External PWM: With EN terminal “L”, it goes into Regeneration Mode compulsorily. Decay current detection is Started to a trigger for the signal of EN “L.” Detection is continued until the reversal signal from COM comes out. Decay current detection serves as [EN] STOP by “H”, and FET is turned on Rev.1.1, May.21.2004, page 11 of 17 M63160J Blank Time of OUT1 OUT2 & OUT3 OUT4 D0 D1 BLANK TIME 0 0 4/ f osc 0 1 6/ f osc 1 0 12 / f osc 1 1 24/ f osc WordSelect0 / 1 of Ch2 Mode Select0 Select1 Select Mode 0 0 OUT3/4- A 1 0 For TEST 0 1 OUT3 /4- B Internal PMWMode select by OUT1/2 & OUT3/4 Fixed-Off Time control of OUT1 OUT2 & OUT3 OUT4 With D2-D6 Toff=(8[1+N]/f osc)- 1/ f osc Where N =0…31 Fast Decay Time control of OUT1 OUT2 & OUT3 OUT4 With D7-D10 0 1 Decay Mode Mixed Slow External PMWMode select by OUT1/2 Tfd=(8[1+N]/ fosc)- 1/ f osc Where N =0…15 0 1 Sync.Rect.Control1of OUT1 OUT2 & OUT3-OUT4 With D11 Decay Mode Fast Slow Phase control by OUT1/2 Sync.Rect. 0 Active 1 Passive FUNCTION With D12 Sync.Rect. 0 1 Disable Enabled Phase 0 Reverse 1 Forward Output turn off when output current leach to zero.
